I can understand where you're coming from, but the basic function of seeint the /roll, "hey i hit a 99 woot!...only to be beaten by a 100...:D" is a fun aspect that can be used in a number of scenarios. Not just for loot in a dungeon. Maybe 2 tanks want to run a FP and you only need 1...roll for it! You made a sweet piece of gear and its going to a BH and both need it, roll for it!....
Seriously though coming up with extra uses for including the /roll function is kinda dumb but I'd do it just to campaign for this issue I feel so strongly about.
/signed....again.
