Like many have said before, spam clicking is a very popular way to be good at pvp. From my experience of not being able to click very fast, TW and SW are very good alternatives that don’t require a good cps. SW is more based on knocking people off bridges and stuff so, just tricking players into bad positions that you can easily hit them off the map. TW is kinda the same but, requires more planning and that kind of stuff.

Anyways Hive is thinking of making changes to PBMM to help solve some problems, I would most likely assume this is one of them. “Additionally, we are investigating taking input type (touch, controller, KBM) into account for matchmaking in the near future. This is mainly aimed at making mobile queues fairer.”
