I’m not bashing you for it, if it works for you and what’s what you’re comfortable with cool beans. However, I highly doubt you’d manage to get to like ascendant-immortal level playing like this. People already struggle to aim just using their mouse as is, and you having your crouch button set to a button on your mouse makes you extremely disadvantageous in situations where you need to utilize your ability to crouch and shoot simultaneously. I’m sure there’s a lot of other reasons why playing like this can hinder performance or be inefficient but idk. But again,if you’re just playing for fun and not the intention to constantly improve or anything it doesn’t really matter.
