Does lowering your arena team's Squad Power change the toughness of the GW???

CG just says too bad. Good luck. Tell you what I do. I try to make it to node 12 with A squad hopefully...maybe 1-2 toons lost. Then I throw my entire collection at node 12 starting with the weakest squad and working my way up to C team, then B, then A. Hopefully by the time A/B get there...I've taken out a lot of protection and maybe 1-2 of the other teams toons. It's still a joke they think it's working correctly. Correctly would be having a matchmaking system that took into account the mods. It's such a joke how overpowered my A team is by the node 12 team. The mods destroyed a fair battle. Their algorithm was turned into the biggest pile of shit when mods were added. Basically they want you to spend $$$ to get your mods all 5dot, A, level 15. Like credits weren't an issue already.
