Yesterday I tanked Tam-Tara reg, being the first time I ever tanked shit in my life ever since I tried to once in WoW like 5 years ago. I warned I was a noob tank and went on running the dungeon.At the end, People even said "hey, gj on mantaining hate".

What I did? simple... I did the thing I like the most when tanks did, even in other games, but most of them are just too lazy to bother doing: I MARKED MOBS. Every. Single. Pull.
You cannot BELIEVE how much love you're gonna get if you do it. Not only that, but you'll also be able to keep hate cuz that rule ensures people will be attacking the same mob as YOU are. My GLD is lvl 18 now, meaning I don't even HAVE provoke.

So, my tip? stop being lazy and mark mobs. Tanking will become really easier
