Let's start with getting someone, I don't care if they are on the staff team right now or not, who knows what they're doing in XenForo because I remember when I was staff there were so many issues.
Focus on content for ONE SPECIFIC GAMEMODE for now that are not pay to win but more so achieveable cosmetics or low-level commands. You wanna keep non-donators, not throw them out.
Revamp crates, like come on no one wants the destroyer and chomper armor or the amount of money it gives you.
ENCOURAGE PVP. Add a KOTH with set chances to win something, similar to the seasonal chest but very much less op. Add back the supply crates, add an outpost, like on Factions, that'll give the player a sell multiplier and some other slight buffs. Just something to up the traffic in PVP.
Just some thoughts, now back to my holiday.
