Will i get banned for not using tank stance all the time in alliance raids?

[Daralii]

Sorry to ask but what MPK means when i'm really bad with abbreviations?

How i can make sure to have second or third highest emnity in normal raids and allaince raids if i ended up stealing the aggro of the boss from other tank just by doing my dps rotation while having tank stance turned on.

I don't know if turning tank stance on and off constantly won't cause some players getting really mad at me, when they already gets really mad at me for activationg tank stance when needed in situations like when main tank dies and when bosses add phase is starting.

MPK is "Mass player killing", which is SE's terminology for intentionally wiping the group or deliberately letting a wipe happen. Using Provoke while your stance isn't on will automatically put you second on threat, so you can just do that periodically if you have a free oGCD window. There are some fights, like Ozma and Cid, where you need to have your stance on because the boss targets the top 3 on threat, but in most cases it's not something you need to worry about.
