Sorry but 3 vokes and 2 WS's (including time to TP to do those WS's) is at least 4000 threat in the new system... the most a Cure3 can do is 1000. So either you are exaggerating or lying. 3 vokes, if you assume all Provoke II, would also take 40 seconds but a tank most likely will die at that point without any heals.

Curaga is insane threat atm and should never be used (3000-4000 depending on how much isn't over healing). I think while tanking I generate about 8000 threat per minute in the new system. Healers spam healing can generate something around 15000 in 20 seconds (and go OOM in the process).

This means? Control yourself, make tank self heal more, make DPS heal themselves etc. You cannot just crazily spam anymore.

Also Accomplice is now the strongest threat ability in the game. All DPS and all tanks should work on getting it and use on their healers on cooldown (and Chameleon afterwards). It cuts threat in half of the person you are using it on and transfers it to you, since DPS threat generation is rather small compared to tanks / healers atm the DPS can use it on healers while the tanks is on CD.
