I would like to see something a little different.
- These tactics use a different slot (ala renown tactics) These slots become available with level -1 or 2 max
Each class has access to these 'core tactics' but only ones that their class can actually use (to eliminate bloat)
i.e Casters can't have STR but has access to initiative, Intelligence, and toughness, Melee won't have access to BS, or Intelligence.
This helps fix classes that desperately need WS in tier 4 instead of the hamfisted attempt mythic did.
This creates choice, you need to decide which tactic is best for you, it will help define your role. These tactics are often an auto include. this way they are still an auto include but you still have to pick which way you are building your character.
People might see this and kneejerk, "you are giving toughness tactics to other classes than tanks it will make tanks useless", or "giving bruteforce to tanks it will make them too strong."
Remember that a lot of the stat increases aside from tactics comes from gear and RR. In order for a class to stack such stats to a cap they need to really push those stats, leaving other stats exposed. A MDPS might be able to have 500 str...it wont do much damage, while tanks that focus of offensive strengths will still be incredibly squishy.
As for tanks that would eschew rugged anyway to go LOLDeeps...we could use this as a replacement for Focused Offensive (a terrible tactic). With access to two tactic slots for this cause (or scales as you level) you can do things like hybrid healing, either way we can have these tactic slots be the backbone of your character, where the "actual" tactics are how you specialize.
You can also have some fun with for balance purposes. if you combine certain tactics this might give you "archetype" Set benefits, adding further benefits for staying within your archetype.
The only worrying one is healers being too tough...but honestly this increase would actually make stacking toughness feasible for healers, and in order to stack toughness your heals start to suffer. This creates another level of depth and complexity to building your character.
