I haven't read every response but I'm going to argue against Jedi Knight Revan. If you've got a solid Padme squad started don't abandon it just to work on JKR. You just unlocked General Kenobi, who is immensely valuable to the Padme squad so you're not quite running at capacity. Once you have the foundational pieces for Padme's team you'll be able to beat the Revan teams quite easily and that includes Darth Revan as well. Shifting to Jedi Revan is only going to bloat your roster
I suggest working towards General Skywalker and focus on rounding out Padme's team first. You should have Padme, General Kenobi, Jedi Knight Anakin, and Ahsoka as the prime four. The fifth can pretty much be any Galactic Republic character until you unlock C3PO, who will become your fifth member. While doing that as your main team you should concurrently be working on Separatist Droids as well, that way once you get the two teams finished you'll be pretty much ready for General Skywalker
Jedi Knight Revan is still a very good character to have but in the game now that team is pretty far down the tier list so while it's something new accounts rush towards the payoff isn't quite as good as several other options. Those people have Revan first, so maybe they perform better in arena right now, but if you stay the course you'll be in far better shape with a good Padme squad and then a General Skywalker team
All that said just decide how you want to play the game. Do you want to be really competitive in GAC? Then don't go for Revan, it'll just bloat your roster and give you bad matchups. Do you want to have a Revan team right now? OK then do it and farm them. Just do what you want and enjoy playing the game the way you want
