Something that's bugged me about ROTE since day 1

Why are we using dark side teams to fight dark side teams? Why are we using light side to fight light side? Shouldn't it be the other way around?

Cls vs clones? Dumb
Jedis vs clones...dumb (Pre 66 I assume)
Trench vs seps...dumb
GG vs seps...dumb

The list goes on. Alot of teams are limited due to their use vs either light side or dark side
