these would definitely help:
1. remove the bonuses for owning bases. just make a bonus for who owns the base which is being raided (1 base) or just remove them..they're mostly lame and people have to waste their time to go capture points in bases which people aren't raiding. it was created to have raids in multiple bases but it won't happen unless era gets 200+ players online at once.
2. remove the script that allows players to kill other when they've already died. it's much more fun when both people have 1 hit left and the first to get the hit gets the kill, now 99% of the time both players die so people spam bullets when you're low.
3. remove bh pk, all it does it interrupt raids which are going on. ulms is enough i'd say.
4. implement deathstreaks. the extra 1-4 dmg would be nice if you've died 2-3 times without killing anyone. players wouldn't be as upset of dying all the time.
