Tank entitlement vs group entitlement

[Granyala]

You're missing the point.
If I get bad player after bad player, I don't care if I time out the dungeon.
If you wanna finish the dungeon with someone such as myself, know your class.

Actually, you are the one that misses the point.
You start a dungeon, you have to play 15 minutes until you can kick the ice mage. By that time, even with an ice mage you should be past boss 2.
Now you kick him and have to wait 5 minutes for a replacement DPS.

Bottom line: you just wasted more time that you would have just going to boss 3 with the ice mage and be done with the dungeon.

This isn't WoW where you get quasi insta replacements. I had a lot of aborted runs because no replacement showed, so I don't see the point in kicking an underperforming player (even if he frustrates me) if the group still successfully kills stuff.

PS: "such as myself", may I suggest you get off your high horse? You are nothing special and this is merely a VIDEO GAME, an entertainment product. This is not (esp not in dungeons) "serious competitive business".
