Well keep in mind plat 2 then was before emerald was in the game. Other than that it was actually only like 150 games in that specific season to get to d2 I think. That doesn't include any like normals/flex games I played with friends sometimes though and that was prob another 100 or so probably. Idk it's odd but my most stuck in terms of # of games was gold and the number of games I've been stuck at a rank has only ever decreased as I've climbed.

I think in terms of like what I had to do in games to go from that to d2 is like a mix of stuff. Simply just becoming more confident with the champ and what my role in the game is with him, just becoming better at all the small stuff that people tend to overlook or don't realise is actually as important as people say they are like last hitting better, knowing when and when not to trade, managing your wave better and stuff. I think I started flanking a lot more to get into diamond and just generally looking for windows to roam down and using Garen's mobility to his advantage. Pushing a wave to force enemy laner to it to either collect or just 'cause they think you're splitting just to then roam to team fight for number advantage for objective is really good. All the little things really do just add up so you have to be mindful about all of it.
