The *real* state of SWGOH (for most endgamers)

If you are getting curb stomped every battle, you need a stronger roster. If your guild is getting curb stomped every battle, you need to go back to Hoth. 4/4 waves on almost every mission is very doable until the last phase, provided you use the right teams, have them geared reasonably well (even G11), and use the mission abilities properly.

Also if you insist there are paywalls in this game, then you are not using the term properly.
