Thank you for that exhaustive information. Will be very useful.The last time I employed the 1-tank-strategy was back at level 65 but the threat and debuff mechanics haven't changed as far as I know. Things are a bit more complicated than described here in this thread.
Lets start of with some basics:
- the debuff can split across a maximum of three people at a time
- the sum of all debuffs can never exceed 210%
- the chance for people standing in front of Durchest to get the debuff is not equal for each and every member of your raid
So basically when the tank steps in too early his debuff will reach higher levels than you will want him to have, that's why the tank should wait for the debuff to build up on the two people standing in front of Durchest, so his own debuff (which he will definitely get once he steps in) stays kind of low (due to the limit of a combined 210%). If things work out perfectly, the tank gets a 10% debuff while your other two guys standing in front of Durchest are at 100%. But even a 30% debuff on the tank (with the other guys sitting at 90% each) is still manageable if the tank gets time to establish aggro prior to the DPS going crazy. Once the Debuffs are settled you got to make sure that no other people (who may have a higher probability to get the debuff) step in front of Durchest to accidently fetch the debuff in place of you original three debuff bearers, also none of the three guys in front of Durchest is allowed to die (if tank dies, a DPS class will have aggro and turn away the boss from the 90/100% guys for too long for the debuff to be renewed on them; if one of the other two dies, the debuff on the tank has room to increase; in both scenarios the aggro is completely borked and the distribution of the debuff gets out of hands).
