Nerf collector?
For the best 3 years or so, the collector has been awfully a pain. The collector for new players who are about to reach uncollected has to fight one of the most bs boss fights ever. The collector has been always like a grind at least 1k units, grind revives, and kill him. Perhaps nerf his regen and e.t.c, but don't nerf him to the brim just make him a hard but fun fights and not having to grind an abundance of revives and units just to kill him.
