I'm in the same boat as you; only my fully-painted set is WoA so that's the one that gets played the most. There are zero rules differences between one and the other; it's just the missions, encounters and monsters that are all different.You're right; mechanical issues can crop up and it can be fiddly at times. I have pretty much vowed to never try playing with 5 players again because it just gets bogged down and starts taking forever. Even 4 can be pushing it -- 3 is a great number of players for it though.
