Strongly appreciated! I get a similar kind of apprehension in PVP games, especially shooters like Tarkov (though that's in part gear-fear), whenever there's basically a chance of the entire endeavour being wasted time - especially when other people are involved, whose time I may also be wasting.
I've got me a macro for a plea for patience set up, etc; I've even gone to the effort of upgrading every piece of gear I could to ensure I'm not lacking in any area. Stiiiiiiill makes it tough.
I think part of it is the idea that, in most cases, folks rely on the tank to set the pace (and then the tank and healer become codependent re: who can handle more/less).
The other part is that, as a Floor Tank main, my instincts are honed to somehow find the vuln stacks or the death-fall edge of the arena. Granted, as a real tank, the goal is to move as little as needed, but still. My clumsiness is still a concern!
I cherish your collective belief, and will think of it when I'm staring down that button again.
Once plugins come back. B/c fuck first-time-tanking without my usual crutches! ^_^;
