Heres just a little suggestion of mine. Don't you hate the fact when you are about to kill someone and some body takes your kill? Well why not add kill assist? You wouldnt be able to get kill but you would be able to get an xp or two depending how much damage you dealt to them. It will be aslo helpful for for people to be a transporter and/or a riftwalker to earn 1xp for a certain amount of people using it (so it wouldn't be xp farmed). Any other xp suggestions can be helpful as well.
Well if we farm Another in our team is noob and it will tag to kill assist and noob able to farm to even they have noob sword
+1 ... This is probably the suggestion i was gonna do cuz archer can just shoot the bow and kill steal your target
I agree on that one, additionally, different types of kills gives different amount of xp, for instance, double kill gives 5xp.
