People neither have the time or disposition to double check your build. All that comes out in the wash anyways. Does it make a difference if the reason why you can't clear with a particular tank player is because they went max Craftsmanship melds or because they cannot push buttons correctly? At the end of the day, you're either not clearing the encounter as a group, or you're finding a replacement. You will, however, get rightfully called out if you can't even be bothered to meld your gear. Lots of people are looking for quick effortless carries, but there's a limit to cheekiness.

I think that some of these stats should be just merged down. Skill Speed and Spell Speed should be merged into a single Haste stat, especially when there are two tanks who use both melee attacks and spells. I don't see why Crit and Direct Hit need to feed off of different stats either, when you could have a single stat affecting the growth rate of both. You could very easily merge Piety/Tenacity down into a context based job/role stat that provided specific bonuses based on what you were playing as. Most of the present stat system is just there for the sake of being there.
