I also just tested in 5 battles the old AOE team vs. Dooku cannon / RG meta. 5-0. Some close wins so it won't be 100%, but it won with bad RNG and in good RNG I had 1 death. Team:
Sid lead, Yoda, Kylo, Phasma, JKA - mix of basics, but heavy AOE spamming from all 5 toons. Yoda for the tenacity up at the beginning. I really don't know why don't build and use these AOE teams to attack more. It's bested every version of meta the game has had since Poe came out.
I'll do some more tests, 5 is a lower sample, but I saw a good mix of RNG in there. I'd guess >70% win rate or so. That's with no Dooku, no RG, no Jinn, no GS, no Rey, no FOTP, on and on. About as non-meta as you can get.
