Planets should be changed so it's not Domination..(Most active players win..and If you get planet with less they just reattack and get) Just scrap it for something else where 1person can attack 5 and still have chance of getting if good enough.
PK arena(was big feature when game came out) it shouldnt be deleted but should allow bounty's(gralats) for every kill there, this would also help players who are new who usually pm me and ask others 'how do we earn money' as mission money etc is pretty poor.
^also to add to that make a starter tutorial ingame.
Squad Spar, yeah but make an award when squad beats so many? else it'll turn out like classic's very rarely used until there is a spar tournement...to add to that make more world events/activities.
Event shop yeah, event house nah not enough players may aswell do come find warper(hint) makes it little bit more fun.
