Basically to keep it short, harass your top lane opponent as much as you can using the Q E combo when ever its up. Use your skills to last hit creeps, especially Q for the Siege Minion and E to clear the 3 Caster Minion.

As for the build and runes, MR is the hardest stat to get on a non AP non mana S3 tank, since they removed force of nature, God bless its soul, so the runes make up that hard to get MR.

As for team fights always initiate like a boss, dive in to almost enough situation, socking up all skills and damage and let your team clean up.

As for tanking turrets, once you have a few core items with W on your health bar wont even move so do that.

Most important skill to learn is when to using the W. Obviously try to have it up when your going to be taking the most damage. Also don't use your ultimate for last hits.

This build is for a early to mid game win. If the game drags out to long (over 40min) the opponent adc will start to roll your face, and your damage wont be high enough for the opponent team to bother targeting you.

Thats it, with W up you can pretty much tank full team + 8-9 turret hits for its duration.
