After the initial clear we are left with a very long time collecting arts and hydro without anything else to do. Intercepters are predictable and boring. Ghosts are mostly the same but can be pulled another direction. Give us actually random spawns with bombers and storms and stuff we need to clear again and defend against. Spawning cerb get harder/more the further past the original 10 min you get. This suggestion would only take effect during rse time so base 10 min are unaffected.
Im sure people will hate this but drs honestly should be harder and more exciting.
