Its not broken, it’s always been difficult. If you Zeta Finn you can do it at G8 without too much difficulty, even the hard tier with some friendly RNG.
Without zFinn you’ll need some highly geared toons if you’re mashing factions up.
It’s ok complaining about having to Zeta Finn but it’s hardly a waste is it?? Let’s be fair he should be one of the very first toons you Zeta because of the versatility of Resistance all over the game.
FYI this I think is the 4th time Ground war has come round for me and the first time I’ve completed both tiers....
