My suggestion for CE...
1) Make non-generator CE farming alliance-wide (collecting items, destroying mammets) instead of those methods only restoring a single party. Imo it would be good to give that assist to the non-generator team but it doesn't make the generator pointless because it's still easier to just sit on a generator and not have to assign people to go gathering CE capsules. At the moment the generator is too much stronger than other methods and while it doesn't guarantee a win, the team who holds it almost always does win. We can't 100% defend from the generator team's constant barrage of machina spam and even so it's hard to find time to gather enough CE for ourselves while on the backfoot trying desperately to defend towers. So our offensive output is flattened while defending and CE-starved, and the machina we manage to hold off don't make a difference because the generator team has unlimited CE flow to replace them. Making a comeback is a lot harder and takes more coordination than staying ahead, just like retaking generator is harder than holding it.

2) Option 2, change how the generator works so it's not possible for one team to hold it the whole match, like tomeliths in Seal Rock get drained and go offline forcing you to move on. Here the generator would just overheat after a while and power down, becoming neutral again and claimed by neither team until a cooldown period passes and it is available to claim again.
