You are not a fail.

Saying someone isn't trying their best isn't calling someone bad. If I sat there tanking 2 groups of mobs and not popping any CD, just relying on shield oath, I wouldn't really be trying my best would I? If you have the tools and the means to do it, and you consciously refuse to do it for whatever reason, you just aren't trying. that's not calling you bad, just saying what it is. Lack of effort, or maybe you just want to relax during the run, who knows.

Or maybe it's lack of familiarity with said dungeon. First few times I run something on my tank job, I only do a couple pulls at a time, once I familiarize myself with the enemy layout to where I personally feel comfortable, I start pulling larger groups, usually increasing by one pack at a time until I find my limit. Apparently this means I'm not giving effort though, cuz I'd rather spend a couple extra minutes killing things than spend double that wiping to trash cuz I pulled more than I knew I could handle
