Let me add to this. When I first joined ROR, I was "sold" on a "DPS Knight" I tried every conceivable setup. Eventually realized Order isbad and swapped to Destro. Made a Chosen. Got BIS gear (Merc + SC Weapon) around a year ago when it came out. Endless SC farming. Now working on new gear as we speak...
What I have realized from doing both a Knight + chosen as well as other DPS classes like Mara and BW is..... Chosen/Knight DPS really isnt good. Sure I can post "respectable" numbers on damage charts in SCs (I play 2H Chosen) but the reality is, its just good ol sustained damage that does help "pressure" but should NOT be the focus of your build.
You should not think of yourself as a "DPS Tank" but a "2H Utility Tank". The Utility is key. Your PRIMARY function is to guard a MDPS and /assist off them. Their damage FAR exceeds yours and if you assist, it boosts the focus damage and the targets will go down (generally). What this means, since you focus on guarding MDPS, is that you need to stack Parry. Good news is we get 25% Parry for free with our ability
So make sure this is up 24/7!
Aside from guarding a MDPS, /assisting, and then making sure 25% parry buff is up (to keep yourself alive) I would focus on parry % chance, Wounds, Toughness. (notice I didnt say strength)
I would say MINIMALLY you should have 500 toughness. HP, should be atleast ~7200+ I run about 8k.
Parry (buffed) should be north of 50%. Use renown levels for Parry/Dodge/Disrupt.
The REST you can put into STR. Its more a "3rd tier" stat after you get Wounds/Toughness/Parry/Dodge/Disrupt up.
This is how you play 2H Chosen. One of the best things I did, was play a real DPS. You will CRY when you see all the "IMA DPS BRUH Tanks" in SCs and just how much MORE effective your DPS could be if they were guarding. It will change your perspective...
Dont do what I did, please... If you want to, go roll a Knight and get off Destro so I can crush you in SCs and RVR. Its not about "damage" at the end of the SCs its about wins and total kills. An untouched BW/Sorc can nuke a solo target with just a few seconds of uninterrupted cast time. If you can live 2-3 seconds longer, or keep a MDPS alive 2-3 seconds longer, it will boost your TEAMS damage by like 400% of what your "increase" would have been if you focused on pure damage.
If you want to play a tanky/DPS class, go play a Mara. Here you CAN focus on DPS first and tankiness second and then come back to me and tell me "oh how right you were" when I read this post about tanks not guarding and you will LOL like me at the idea of "DPS Tank"
That said. I love my Chosen. Worth the time to level and play. Correctly.
