What team to focus and Zeta?

If you’re looking for a good arena team revan is hot right now. However he requires a good amount of investment. Maybe wait until you know what’s needed for darth revan and farm for him?? It’s hard to say. If you want to be a top contender in arena you need good mods and to stay on top of whatever the current meta is which most likely means spending $$ to keep up with everything.
