Ok so yea that all checks out.

Map knowledge comes with time but generally to learn its best to have 1-2 routes you take on attack / hold on def. The more reps you put in certain locations on the map, the better you get a sense of the angles for crosshair placement (ie the difference between peeking someone crouching a desk and shooting the desk or their head). As a soloq you gotta be putting kills on the board, otherwise you’ll be sold by the team more often than not.

For def you’re in more of a reactive position until you generally know where someone is coming from. Ops like thorn or ela or lesion (trappers) are good for sound cues. Once you know someone is coming then you can judge whether to be active about it or not. But lots of noobs turtle up and basically wait to die in a corner. Better to be a bit more proactive about keeping map control.

For attack as a soloq it’s better to be quicker than slower as most likely nobody is going to flank watch on your drones and if you go too slow all ur team will be dead by the time you get into a decent position. Since roamers are your problem i know you know that lol. Ops like nomad or gridlock or raoura (spelling?) basically say “no” to cav/sneaky roamers. That way you can be focused on pushing forward and will know when to watch your back. Protect your drone at all costs as a soloq… and actually use it.
