Tanking requires leading the way. It requires knowing how, when, and what to pull. It requires good positioning, it requires keeping a constant eye on what your other groupmates are doing…It requires a lot of skill in terms of when and why to pop which specific cooldowns you have available to you.
Most of all, it feels less rewarding than other roles because you’re not really putting out damage or getting many “epic saves” with big heals or flashy cooldowns. You’re either getting hit or you’re not getting hit and getting hit is about the only thing you’re supposed to do on a conceptual level.
It’s a role that’s got an extremely high stress load and an extremely small payoff. Plus, healers and DPS will usually blame you when something goes wrong–especially if it isn’t your fault.
I used to tank a lot in WotLK on my DK and in Cataclysm on my Paladin, back when tanking was still kind of fun and felt interesting to me. I kind of tapered off of it after that.
Come time for WoW Classic, I realized tanks were in seriously high demand, so I thought “Hey, I can tank, I’m a paladin” so I respecced and got an instant invite to a Zul’Farrak group. I told them I had just respecced and was still getting the hang of tanking, and since I’m a paladin I would need a few seconds to get hit before the DPS could start spamming AoE.
So what happens? I walk up to a group, threw down consecrate, and right as I’m clicking Holy Shield to get some block threat–the warlock runs in on his MOUNT and then drops into the middle of the trolls and starts HELLFIRING.
He obviously pulled threat and died instantly. And then he blamed me. I explained to him that my threat isn’t really high enough to counter Hellfire spam right off the bat, and maybe it’d be better to single target and assist me to make sure I have a better chance of holding threat.
He then went off on a tirade for the entire rest of the dungeon about how I was a trash paladin and how a good paladin shouldn’t have to drink between pulls and should just have infinite mana because of blessing of wisdom…
And then he left when we hit the temple with the big groups of trolls. We finished the dungeon 4-man and I went back to Stormwind to respec and then I never tanked in Classic again.
