Any tips to get to Unreal?

Right now I’m on Platinum II, playing mostly on Zero Build and I don’t get as many kills as I’d like… mostly one since I tend to avoid dangerous fights and I usually find myself between the ten last players. I’d just want to ask if any of you have any tip to rank faster. Don’t get me wrong, I’ve been ranking up just fine, I just wanna see if I could be doing more, specialy considering the ranks will be reset in a matter of a week and a half. Though I might just keep going on the NeXT season lol
