I'd love to see a XP bonus/malus game mode where team players could kill each other. When you kill oponent, the XP process remains unchanged. When you kill team player, the XP process would be exactly the opposite of oponent kill XP process, ie, you loose XP. I would suggest to enable negative XP generating negative Gold for really bad players... That would create a very different game where splash weapons would have to be used with accuracy. Additionally, bad team players would be penalized if they kill team members given they could loose some gold if they reach full game negative XP. just thoughts...

That's improving the process, but this is not enough. Micro-upgrades are way too expensives in cristals, ie, if we want to improve from smoky m2 to smoky m3 with micro upgrades, il will costs 456620 cristals vs 268600 cristals if you directly get m3. What looks to be an advantage is still very unfavorable. However, if micro-upgrade costs were exactly aligned with the buying level up equipement cost, that would be a good deal for players and micro-upgrades would definitely be a good alternative for improving equipments.
