Yes, you can, and if you feel that will make you anxious or stressed, it's better to avoid them. I've played a couple of competitive games in the past and have even secured server ranks, but unfortunately, I don't get the vibe in Tower of Fantasy's PvP mode. It's just my view despite the mode being balanced. For the time being, I'm sticking to Bygone Phantasm as I don't have much time on hand, while I'm also playing Genshin Impact at the same time and avoiding PvP modes.
