Simply put, I just ran 2 straight raids with 6 Tank Specced people. This keeps happening and I'm sick of it.
Bottom line is if 2 people Queue as tank, those are the only 2 players that should be permitted to spec into a Tanking spec. Create a spec check system, if a tank leaves or gets booted, permit 1 more tank to spec into that build.
If a wanna-be wasn't dedicated enough to run Heroics/Dailies etc for Healer or Tank (or DPS gear for that matter), then they shouldn't be permitted to ride on other people's capes to get the loot they want.
This is ridiculously unfair to everyone that does LFR whether they are DPS'ers, Healers or Tanks.
I don't care if there's other threads about this, frankly Blizzard needs as many threads as possible.
Ideas: Create modable party roles.
Queing as 1 of 2 tanks would give 2 Raid Roles as tank which can be selectively transferred by the queue'd players decision.
Same for DPS and Healers. If people are scared of baddies, create a voting system to vote a role off of a player and transfer it.
Set the role to disallow any loot for any player that attempts to play a role they are not specced for.
FIX IT NOW!
