This is the first post of a series to overhaul morales for all careers where it's needed as there are some major discrepancies as well as certain morales being too weak or too strong in comparison with everything else.
Keep in mind that ideas may change if they don't work out, as always. And time to implement may vary as we will probably not be able to make all changes at once.
As an overview:

General for tanks:
M4
Immacule defence will be lowered from 75% to 60%. This morale is simply dwarfing the other morales and is still strong at 60. It should be worth getting the speccable M4s.
M3
NEW ABILITY: Hold the line: Will be an instant 30% HTL stack for 12 sec to all members in 100 feet, will require a shield. This is as tanks are support when using a shield and not a dps. This is given as raze will have a 2h requirement.
Raze: Will have a requirement of a 2h weapon. This as tanks with shields are support and not dps.
M2
Distracting Bellow: Its range will be increased to a 45 feet cone and reduction reduced to 35% instead of 50%. Bigger range to make it easier to hit with consistently but less power in return.
Specific Career changes:
Black Orc:
M4
Puddle ‘o Muck: Change to a instant 1200 dmg but keep snare. Damage was crap.
Can't touch us: Will be changed to instantly give party in 100 feet 200 AP as well as a 4500 absorb shield. Made to match shield of Valor as it was clearly stronger.
Yer nothing: Entire rework will be 300 dmg each 0.5 sec with micro knockback in a 30 feet range. 3 Sec duration. Original implementation was simply crap with no damage and a small morale drain.
M3
Deafening bellow: Silence component will be removed and replaced with a 1sec buildup increase debuff for 10 secs. Slightly longer duration but made worse as a 5 sec silence to all hit in an aoe is very strong and made all other choices no choice.
M2
Walk it off!: toughness component removed and will be replaced by reduction of crit damage by 25% for 20 sec. Toughness is less effective and this change would make it interesting in the crit meta that DPS dealers usually build on.
M1
Quit yer squabblin’: Total rework, single target silence for 7 sec. We wanted to give the BO some single target utility fitting for a M1 which can stop a healer for 7 seconds.
Chosen
M4
Warping embrace: 1200 damage in a line with 40% snare over 15 sec. Damage was crap.
Shatter faith: Total rework to match solar flare. 30 feet aoe with 800 damage and drains 1200 morale of all hit. Original implementation was crap as it was the damage with a simple dispel.
M2
Tzeentch Amplification: We are open for suggestions on this one, its rather bad as it is and would be up for a change that fits with the theme and name.
Blackguard
M4
Blast of hatred: Total rework. 1200 dmg instantly and knockback in a 40 feet line. Damage was crap.
Khaines warding: Total rework. Increase avoidance on party (not BG) by 20% for 15 sec and the BG gains a 3000 absorb for 15 sec and 100 hate. Original implementation was crap as it was a small heal dependant on a block inside the party which would most likely only be from the BG himself...
In Malekeiths name: 45 feet aoe with 1200 dmg and a +10 cooldown increaser for all hit that last for 8 sec. Increased range and changed silence to CD increaser to make it easier to hit with and to still allow it to be disruptive but not too strong.
M3
Armor of eternal servitude: Will have its heal increased to 7200 over 20 seconds. Original implementation had a crap heal.
M1
Banish Weakness: Healing component removed and instead gives 20 hate instantly. The heal was crap and with the hate increase you can dump hate and then use this M1 to get defensive tactics again and/or another hate dump.
Ironbreaker
M4
Strength in numbers: party avoidance lowered to 20%. Original implementation was simply slightly too strong.
Earthen renewal: Total rework. Party in 100 feet will have hexes, curses and ailments removed and buffed for 10 seconds with “on enemy cast deal 400 dmg back to attacker”. Original implementation was simply crap and not worth taking in the tree. This way the IB should be able to turn the tide possibly in a tight spot with the damage back.
M2
Skin of iron: Total rework. Disarm attackers on melee hit for 10 seconds. Compared to the standard M2 with 100% block this should not be taken unless 2h which for a generic morale is not ideal.
M1
Rock Clutch: damage increased to 900 and root reduced to 5 sec. Slightly more damage for the IB instantly and then lower root to make it more tempting to take over demolishing strike.
Knight of the blazing sun:
M4
Flawless Defense: avoidance lowered to 30%. Original implementation was simply too strong.
Solar flare: reduce morale with 1200 instead of full morale wipe. Original implementation was simply too strong as it could negate an entire push from the opponent force in a crowded defense. There was no other morale with the same power and has to be tuned down.
M3
No escape: Total rework. 900 dmg and 5 sec root in a 30 feet aoe. Original implementation was simply too strong.
M2
Emperor's Champion: Total rework. Removes all CC (like juggernaut), CC immune and 20% move speed for 10 sec. Original implementation was simply too strong, giving too much “free” stats on something that you can in practice under the best conditions have a 50% uptime on. Instead it will be a ability to make you close to impossible to escape from.
Swordmaster
M4
Shadow Blades: morale drain removed and replaced with a choppa pull effect. Morale drain was simply bad and replaced with something more fun.
M2
Wings of heaven: open for suggestions here. But it has to be replaced. Order already have more gap closers and this is a heavy armor wearing tank career, a pounce does not fit here.
M1
Guard of steel: toughness component changed to a party increase of 800 armor. The armor increase fits better for fluff and also makes it more useful against melee but less useful against magic.
