These changes sound great. I agree with RipeCoconut's comment, "Sometimes I want to play a champion the way I want to play that champion, not the way everyone has to play that champion." In order to avoid a verbal assualt, I just go with the same summoner spells and item builds that everyone expects for support, or the tank, etc.. Keeps the harassment down. But I have found builds and playstyles that work for me and help win games, but are might fall outside the current trend for each role. One example that comes to mind: if I play Sona and build the standard build and go with the standard summoner spells, and, if the carries fail to carry well, I have no chance to take the solo lead and turn the game around. However, if I can build to support then convert to aggressive if needed, that would be great. I hate to be doing well as a support player (not that I always do) and then to find myself stuck in a losing game where the other players refuse to conceed or admit defeat and find myself stuck playing out the slaughter with no way to turn things around.
Anyway, go Xypherous!
