Between myself and Ron on my leaderboard we both switch out who is number one in our time slot every day.
That said, I have yet to see this Poe meta (the full on Poe, FOTP, Leia, Sid, Lumi). Sure, people use Poe (I started just to see if it mattered much), but, to be completely honest (seriously, I am), I haven't noticed much difference. Versus the AI everything is stupid easy to win. Ron and I (and Merkal if he's playing that day) routinely beat teams six levels higher than us to get back to the top rank... Poe or no Poe. One of the guys from another time zone has the closest thing to this Poe meta I've seen on our leaderboard and we still knock him back from his top ten spot every day when our time comes. He was using Poe, QJinn, Sid, Lumi, Dooku (sometimes Luke) today... Was beaten severely in under two minutes by Poe (5* no less!), Sid, Lumi, Kylo, JC even though his Poe went first. His team gets bumped back regularly by some of the Chinese teams who are still running Bariss as leader (no Poe) even!
Seriously, people are arguing about a Poe meta that, frankly, doesn't even exist for 99.999999% of the playerbase.
Who really cares about the top 10? Those of us there know darn well it's more about strategizing timing and battle lockouts than actual in-battle strategy. If you have a high 'wallet warrior' count on your leaderboard, then it adds the dimension of how much you can spend for 7* Dooku, 7* FOTP, 7* Leia, etc. Some can be f2p'd but, come on, Dooku or FOTP at that level without big investment? Maybe in 3++ months. I've been farming Dooku for a month and barely unlocked his 3* rearend a couple days ago. The meta isn't feasible for f2p. Which is the way it's meant to be for $$$$ for CG/EA. Motivated to pay $$ you will be.
Seriously, 10k+++ people in each leaderboard and people are arguing for a nerf on a team only top 10 'wallet warriors' on older leaderboards are using? REALLY?
Let it go...
Go listen to the Frozen soundtrack a few times. It's inspiring.
