Long, short story:
Am bad-to-average FPS gamer, looking to improve. Saw an OSU! gamer flinging its “shots” left and right and tried my best to mimick the experience in an FPS. And it worked significantly – all of my shots felt more “secure”, even with my aiming being rusty beyond belief.
And the “trick” to do this is simply leaving your “aiming hand” to aim (ONLY) while leaving your “non-aiming hand” to shoot and everything else. That’s it.
i feel like this set up would be best in a game that is very spammy with mouse clicks, say Minecraft 1.8 pvp. i don’t know how those people do it, but given 2 keys to press on my left hand rather than 1 on my mouse, i could maybe stand a chance with the clicks per second.
