I have recently done nWGT with my DD and there was some stamina DK tank was quite strange experience. The tank had >160cp AFAIR.
After multiple runs with my mana DK tank, I would have have expect the following from DK tank as group services, and many DK tanks really do some of it or all of it:
- Taunts for hard mobs and bosses
- Talons for CC-ing mob packs in compact group
- Chains or ranged taunts to take off mobs of healers and ranged dps and group mobs for further burning by AoE by DPS.
- Ingenious Weapons all the time (for high DPS parties I sometimes had no time provide anything more)
- Ingenious Shields if party have survival problems (like 15K stamblade fighting engine guardian or end boss in vCoA)
- Not walking bosses and hard mobs around unless there is real need to do so and dying rarely (so self heals, armor buff, etc)
This all requires mana to sustain, but not that much mana as I understand. Ingenious Weapons and Ingenious Shields are even useful for converting mana to stamina.
The only thing I have see were taunts, and armor buff. Tank walked constantly pulling big mobs around. No other services to party were provided. Even to chase portals, the tank was using charge ability rather then chains. That tank declared that she is stamina DK tank that she does not even have Ingenious Shields, and said "mana DK tanks are horrible" or something like it.
So I'm interested, if there are real mana sustain issues for stamina DK to provide all these services to the party (so possibly I'm expecting too much). In that case, I'm interested what services could be provided by stamina DK tank, that could not be provided mana DK tank to balance that. The survival of that stamina DK tank was very low (daedroths kill her almost on half of encounters), as no self-heals were used possibly except for bottles (both vigour and dragon blood have visible animation), so survival is not the likely service.
