@djsuursoo: Good tanks, great tanks, and elite tanks - are all largely unknowns thanks to LFG tool meaning nobody really knows anybody anymore anyway. You might have one and you might not and might never know the difference either way unless you've been lucky or unlucky enough to see the other end of the spectrum.

There are very likely 'elite' tanks stuck in LFG-random-PUG with a dead guild because they don't know they're good enough - or don't know or care to leave guild for 'greener pastures'. There are likely bad tanks maintanking top progression content every week because the group is used to them and 'handles it' or just assumes this or that is slowing progression but doesn't know to analyze their tanks.

I'd say the odds are even either way these days.

The last time the tanks on either of my servers knew who the other tanks were was near the end of BC... Wrath hit and even casual guilds were raiding so everyone turned mental focus inward. Then LFG hit and people and community just went 'poof'.

You're lucky these days if you even know your own guild's tanks... especially as guild XP encourages super large guilds.
- Your best tank might be that guy sitting on the sidelines who hasn't bolted for the door yet. Or might not be.

WoW has become anonymous.
