1) If you manage to keep that tank who refuses to pop cooldowns or tank stance and is undergeared alive the entire dungeon, you get no comm. But if you're that tank, you're triple comm'ed.

2) The pony is reserved for the worst player.

3) If you aren't a female Miqo'te or a female Au ra, you're minority and thus S-E don't like you. And if you're a male Lalafell, the community also hates you or wants to use you as food.

4) Healer dies at dungeon = wipe. Even when there is a SMN and/or a RDM alive. Exception only when the boss can be killed before the last regen tick.

5) If you have 99% chance of hitting something, you'll miss way more than 1% of the times.
