Anyone know why GM's and group posters are so selective about party members? I've been playing D&D and pathfinder for years (never on roll20 until recently) and the only thing I've ever encountered are so loose rules about not working against the party or about having some diversity in ability. Here on roll20 it looks like everyone is trying to optimize and custom build their campaigns to desired specs-which seems completely contradictory to the desired suspension of disbelief you can achieve with this wonderful game. I take no personal issue with this - just curious if my in-person experiences have missed something that the online community finds important.
