The most important thing is to make good trades with q and hits (even passive hit) from lvl 1 to keep your opponent under 40%hp (you need like 2 succeed q) !Against range opponents you just can poke with passive and use e on minions as gap closer. If you do this , any time you have a chance(even if flash needed) to hit e on the wall , you have instakill , even as a turret dive! With a short advantage you can even 1v2 when ganked.. Late game you almost instakill non tank units when you hit e on the wall and still be a tank ! Easy way to get to plat and even more.
