Gone warrior tank on dreadmist, already had dps and a healer in our group, so thought I’d try tank out. Never played a tank before on wow so will be learning off the bat. Hoping I don’t suck too much once I get to dungeons lol
Been a warrior tank main since BC. It's fantastic fun. It can get hectic at times, my best advice is to learn what tools you have available in your whole group, not just you. Stuns, CCs, etc. Ask for the lead spot and mark stuff up. Learn to strafe kite (youtube it) and get some good tanking addons. I used tidy plates & threat plates, and get some form of debuff timer. It's all about knowing exactly which mob has which debuff and making sure you're applying them in rotation, particularly sunder armor. Try keep that up at all times on all mobs, then rend, and if you're taking loads of physical damage, then thunderclap. It'll take practice, you'll be the cause of loads of wipes in the beginning, but when you master it it's the most satisfying feeling in the game, and I talk with 10 years experience here.
I've never mained a DPS, always been a plate tank (warrior / pala / DK), and also healed quite a bit. If you want to heal for a bit then go for it, you'll learn tonnes and it'll improve your tanking dramatically as you'll know exactly what your healers are up to and what you can do to make their life easier.
Good luck, don't be afraid to ask, and make sure you tell people you're new so they manage their expectations. Many will even offer advice and tips, but you'll obviously also frequently get Jonny the 13 year old who whinges and whines. As a tank you need just as thick a skin out of the game as you do in-game, you are responsible for the group after all.
Oh and planning. I don't mean each individual fight as you go, but if you know you're gonna run deadmines in the evening, then research the fights as they're actually a challenge again compared to retail. Knowing what to do and what to expect is 90% of the job done.
Also pick up mining for the +stamina buff and grind it out. Grab any potions, buff foods, anything you can to make yourself tougher. That's your most important thing. Forget DPS at first and concentrate 100% on survivability. Once you gain confidence in your tanking you'll need to focus on your Threat Per Second (TPS). I'm getting ahead now however, just focus on staying alive.
Then at max level you'll start learning about hit cap, block cap etc.
It's immense fun, good luck!
