In my opinion, more people doing PvP is always a good thing, we could always do with more growth. If only a small amount of people who try it for various reasons, enjoy it enough to stay on long-term and practice to be good, then PvP stays alive in this game. The mode is new and this is pre-season so try not to worry about win/loss record. There's always going to be RNG anyway when you queue solo and the other team has the same luck of the draw.
