General mistakes you're probably still doing
This aren't in any specific order, just placing them as I'm thinking of them.
Not using your max ranged to prevent shorter ranged brawlers from feeding off of you.
Running too far from the action: When you're too far, you're incapable of helping your teammates or finishing off an enemy.
Not scouting properly
Not contesting a lane: against certain brawlers like a thrower or Rico, there's not much you can do so it's expected, but when it's an even matchup you don't want the enemy to push your team into a corner so pick a lane and fight.
Lack of awareness: some of you players get so focused on something that you miss out on an enemy pushing into your grass, an enemy pushing your teammate, or forgetting an enemy has their super or stun gadget (talking to you players who walk into dyna stun)
Aiming and auto aiming when you don't need to.
Being too afraid to do plays: there are times where some of you players play far too passive, and while I understand not every play will be a good one, it's up to you to discern whether it is or not.
There's always more for drafts, maps, modes, etc. But I'm sticking to general for this one.
Edit. I'm still adding more as I'm thinking of them, lol.
- Not healing when you need to: I often see players at low HP when they can't really do anything, so dont delay the heals. it's pretty frustrating seeing players do it.
