First of all, i love this game. Back in the day i was making a montage but sadly it was unfinished.
Some suggestion:
More items, Make grinding better. Play to win vs pay to win. Old MA was easier to grind.
UM, More items!??
Also, some new maps wouldn't hurt. It's definitely something us players would like to see. Or maybe even more zombie specific or PvP specific maps. The old MA didn't make new maps due to them wanting to shut the game down. Given you guys just opened up, it'd be a good idea to get someone to start on some new maps in the future, even if it's not for months, It's a good idea to work toward that. It'll keep people around, along with giving new items to use, will also keep players around to farm them out.
There needs to be set points of goals where players feel they want to reach. Like in mmorpg's they have job advancements once you reach a level, giving you new skills. Now, i know thats not the case here but there should be something to that aspect, A grind to reach a goal
