recently i have often get DD pretty rude or maybe dumb... i don't know.

i means, i have work my ass to get my tank to 50, get to know every monster weakness or pattern of the dungeon. and often they come and decide what i must tank or not...
hello, i know the dungeon, the limit of my tanking, let's me pull and decide the order.

i will not talk of the DD in relics +1 that shoot all they have in less of 5 second at the start of the fight...

i can understand people thinking that tank are rude and jerk, but sometimes i wonder if they think about our viewpoint?

we don't ask to focus the same target for nothing!
we don't mark this target for nothing!
we don't do this in this order for nothing!

they need to understand that we are not simply checking if our rotation of skill is good, we have to check the hate meter for each monster (can be kinda tricky), we have to keep an eyes behind our head for make sure no one aggros. we must keep in mind the dangerous skill than a monster can have, we need to be ready to avoid this AoE that will make the healer in pain! we must get ready to interrupt whatever we have to interrupt!

Gosh we have a more complicate work than DD, let's us do our jobs!
