Any advice would be very well received
Execute is a no-go on first round. Key to winning is Boba ability block - you need to get block on chirrut and at least one of Baze/Biggs. Otherwise it will be almost impossible to win, unless you're faster than him. Key for first round is to fire all aoe skills so your sth fuels other TM's before Baze dispells it. He is a sacrificial pawn, nothing more. You execute in second round, be it wedge, chirrut or baze.
Once you reach the point that Lando is 7* and you can't farm 5* health mods yet, you recomend that we farm GS. Wouldn't farming TFP work just as well, or is GS's ship better? Seems like TFP as a toon has a better kit.
TFP is a better overall unit, but needs debuffng allies to work best. GS is a stand alone unit that can be plugged in anywhere. His ship synergises well with Ackbar and Sun Fac ship. Both will be needed in the end, because you do need 5 dark side ships at 4* for ship challenges (higher tiers in the future as well). Overall TFP ship is squisher so unless you have some tanks to protect him, he won't do as well in arena from the start. I have him in my squad, even on 2* pilot, but I run Sun Fac and Biggs beside him. GS is my MVP atm, because he assists and crits a lot.
Great f2p squads to aim long term (definitely better than Wiggs squads) are Zader, Palp, TFP, Boba, Shore or Zaul, Vader, Palp, Boba, Shore.
You do need a 7* rebel team to get to this point anyway, so Wiggs teams have to be farmed anyway since those teams are crippled w/o Palp.
Actually, those are pretty much meta
Yes and no. Can't say that smth is meta if it has a hard counter and Rex can be considered that, but only if fully geared for speed. Having said all that - empire teams will be a staple in the future. However a team of Rex(L), Boba, Sun Fac, Lando, JKA is a very nice counter to empire teams.
