The point for Combee is more or less based on bees serving the queen of the hive, hence Vespiqueen(at least, I believe so). Wynaut and Wobbuffet are pretty much the same concept, different Pokemon for different tiers, with more or less the same moves.
Also, Encore isn't so much a great move anymore since it got nerfed in 5th gen from 6 turns to 3 turns(I think), so it's more or less kind of useless. :x
Never said it would be OU. It'd best be safer in something like NU or RU, tbh.
