Hi i found this interessing problem with DRK as off tank, u cant play for more of 2 minutes.
Why? Because you run out of TP. DRK is Mp based, this mean that u must use OCD to regen it as u can to encrease DPS and tanky stuff, BUT as offtank u Have BloodWeapon, gr8 skill to regen Mp BUT this will make you run out of tp simply coz increase your Skillspeed and testing inside dungeon/raid and testing on dummy i saw i cant offtank for more of 2min/3min.
I open this post coz every class have some way to regen Tp. DRK have no way.
Dont say pheon or goad coz like i sayd all class have some whay to auto regen or selfsustain a long fight but DRK
I hope this will be fixed by givin to drk a tp regen skill or lower how tp cost like ninja
