I have run into my share of tank haters. Mostly in the lvl 50 dg. Most people fell to realize that some player are learn the game just like you once had to they are going through the dg. to learn the ins and out just like everyone else. And yeah videos help but you have to learn it for yourself. I admit Im still trying to get my relic but i know i Need higher gear so im running dg for tomes. I like to get them over with also. So before you jump to hating run the dg and if you finish it then it was a good run. teach the other players the better ways and they teach others the community as a hold become better.
