Gonna rant...
Why do monks get unique icons? I don't know why, but this is bothering me for some reason. Monks are already different than the other base classes. This is kind of silly in my opinion. If you are going to give out unique icons, do it to all the prestige classes, or better yet, don't do it at all.
I can only think of a few spots in the game where this differentiation matters to the party leader ~ ToD comes to mind at this early hour, for anti stun. But you don't need an icon to convey this message, you can just ask the monk in question, or ask through /tells before he joins if it is that important. I can also, sort of, see people being declined without question based on their prestige classes, but we'll see.
But seriously, what is the reasoning behind this (anti stun vs. no anti stun, really?)? I hear people ask the following all the time: are you warchanter or spellsinger, are you kensai or defender, are you knight of the chalice or defender, etc. etc. and I am positive there will be even more questions with the new sorcerer enhancements.
My bottom line suggestion is, don't do unique icons, keep it simple and easy. Make people have to communicate with each other, that is kind of how the game is supposedly set up, where communication is key. (I know, I know, graphics/pictures are worth a thousand words, but c'mon)
My not so bottom line suggestion is, if you *MUST* do unique icons, do it for all prestige classes so everyone can feel special, warm and fuzzy and so that everyone will have an equal opportunity to be auto-declined based on their prestige class.
Other than that, the new mod looks fun.
