Hello.
I'm the OG Dota 1 (WC3 Custom Game) player from like 2 weeks ago who started playing league and had asked for some character advice from people.

I hit ranked level 41 \o/ but I'm really really struggling in games now. I started off playing Briar in the Jungle role, then switched to Naafiri (I like dogs), and then played a lot of Kai'Sa games but I've been losing a lot
>no like, a *lot*
of matches and it's starting to demoralize me.
I believe I'm something like 19 ranked wins and 30 ranked losses.

Is there something I'm missing? I've jumped around on a lot of different characters and I can't seem to lock down on a proper role or playstyle any more or even character. I don't feel impactful or that I die far too much (I'm dying around 10 times a game and I'm getting around 5/6 kills a game). Perhaps too aggressive but that's sort of how I like to play but that doesn't seem to reward me ever.

I've got some token free currency and I bought a bit of RP for some cosmetics, I didn't want to buy too much but there's some skins that are pretty or that I liked the look of. I'm just really struggling.

I'm not sure who to play any more or where.
