iZone needs more of its core elements from the server it came from. Less squad-related content and actually make use of planets like Iricia, KotH, Gwars, etc. and make them a team vs team map vying for their objective. I understand that squads bring in revenue, but if Zone actually distanced itself from other servers and made use of Zone's guns, vehicles and maps in the way they were made, you'd probably bring in a fair bit of players once word gets out as Zone was loved. People that I've talked to and played with or who've tried iZone years after trying PC say it's utter trash due to the fact that it is nothing like Zone and is just a carbon copy of every other iServer with the way it's handling guns, health, social and PvP aspects. When GIT was working on guns he was bringing back that good PvP side of Zone and a few players actually came back because it was starting to remind them of Zone.
TL;DR: Less squad-oriented focus and have more 1v1 fixed teams with auto-balance and such on planets (Teams such as Storm Troopers and Raiders). Put rewards for winning if you want, but it needs to be less squad-oriented and the server needs to define itself more, instead of taking everything from the other iServers. I could go into more detail if you want, unless this is enough.
