The only change I would possibly (possibly) like to see is more XP for assisted kills.
Right now killing a player is worth a static number of XP, depending on their level. If someone gets the kill solo, they receive full XP. If there are assists, the killer gets reduced XP and the assisters get the rest. The killer still gets the most, but the overall XP doesn’t change.
This actually incentivizes bad play. Diving too deep for a kill will earn a full XP load for the diver, but the opposing team will have their XP spread across everyone who helped.
