Bad idea having first character as a tank?

[Gula]

Just tell your teammates at the beginning, that its your first time in a dungeon. Then they know that explanations are probably needed.
For normal dungeons thats enough.

If you get lvl 50 and want to do some extreme primals or raids, pls watch a video first and do it with partyfinder, not dutyfinder or with friends/fc mates that can explain on the run.

I disagree. I got through all the ARR Extremes without a guide and synced. Those, like literally any piece of content, can be done when people talk to each other in an MMO.
