Since I'm reasonably durable, and because I know how cahllenging some fights can get, I am usually pretty lenient with Tanks. This is especially true with a lot of mobs, and even more true with a lower geared tank. If I'm not attacking the same target as the tank (either due to stupidity on my part or target switching on theirs)it's pretty darned easy for me to yank aggro.
As long as the healer doesn't bitch at me (which has happened once recently, in HoR during the run from Arthas - though the tank wasn't bothered evidently) I don't sweat it much.
The only time I will get a bit testy is when the tank is reasonably geared (at least from a GS number - as mentioned before, I don't inspect folks - I don't have the time) and when the healer keeps getting aggro, and I have to keep playing damage sponge because I have to keep taunting mobs off the healer.
Sometimes I think the healers are standing a tad too close, but with so many fights I realize that LoS is an issue, so that they NEED to be close-ish.
Then again, on other fights like the current Holiday Boss (Athune), with the bevy of mobs that keep spawning, I can fully understand how it's pretty much impossible to keep all the mobs on the tank. In these fights (especiall with a lower geared tank) I will actually turn on Righteous Fury and run as Off-Tank to help keep mobs off the healer. (an interesting PuG story about last night later in this post)
So, I am understanding, but when I see a tank NOT doing the basics (consecrate, stomp/whatever) to at least get SOME aggro, I will groan, and bitch to myself. As long as I don't get bitched at ("Watch aggro, nub!!"), I'll suffer silently.
Tanking from the the sword & board perspective:
I can sum this up in 2 words:
Especially on nights like last night, where I offered to tank on a 4/5 guild run. "Unless we get an ICC heroic, then I'm bailing".
And what do we get?
I wanted to bail, but the guildies said "nah, you'll be fine".
As ide from a slightly overeager group of DPS on the first couple groups, things went smoothly all the way to Ick & Krick.
We didn't wipe, but we did lose 2 DPS. But, I was happy with my performance overal to this point, because I kept the mob moving out of the green, didn't get more than one at a time, and the actual Boss fight seems to have gone well enough.
And then came the ramp from hell. You know, large groups of multiple mobs, including several casters? Yeah, that slice of hell.
We didn't get there quickly enough to avoid the first 2 groups, so we slogged our way up. We had a couple deaths and a couple REAL close calls, but we still made it.
I was asked several times if I was using Consecrate, and yes, I was.
If you're at all interested, my initial way of going in was:
Start running in
Hand of Reckoning (to damage one, and also to taunt)
Avenger's Shield to further taunt, damage, slow and silence
Drop Consecrate when I get into the middle to get more AoE aggro
Hit Holy Wrath to stun them and get even more aggro.
And then try to tab-tab-tab-tab. Which never works all that well. It will select a new target, but often will not actually TARGET them, until I cast something.
This means they will have the red circle below their feet, but my toon will not auto-attack, and some spells won't cast. (fortunately, Judgements will, as will Crusader's strike)
So, we slowly trudge our way up the ramp.
From there on out it was pretty easy, with only an occasional Righteous Defense.
The final boss fell without much ado.
So, I can fully understand loss of aggro on large groups, but there's still need for SOME work.
(by the way, if you read this half way through, I inadvertantly hit [enter] twice and it posted it.)
