“Proper” being the key word. I’m just recently a silver border and I’m in silver. I’ve put in plenty of hours, but just kind of playing on auto pilot and messing about. I’ve developed loads of bad habits (eg booping enemies on reflex, sending them away to safety rather than just shooting them dead) that will take a while to fix.
I’ve received critique on a couple of vids and have about a dozen things to work on. I’ve already improved a lot in a very short time, but not yet reflected in ratings increase as relatively few comp games played, so subject to a recent run of bad luck. But I am definitely better than I was even up in 2.3k.
Death Match. Play loads of that. Most time efficient method to improve mechanics.
