I tried out Galio, and I did much better. I got 2 kills in each match I played with him. I also use Heal now, and I retreat at times. And I buy equipment that I feel would give me an advantage(That armour that revives you, for instance.)
You have to knowwhen Thornmail is good and when it's a waste of money, but that build should work as long as the enemy team has 2-3 AD champs. If they have more than one AP champ, you're going to want Banshee's Veil before Thornmail.
Keep in mind that if you build Warmog's, your opponents will almost always counter with Madred's Bloodrazor. You'll need more magic resist to counter their counter, since Madred's deals 3% of your total health as magic damage. Without any magic resistance, you're dead in 15-20 hits, since the Madred's damage is added to any damage they were doing before... That's why Teemo is awesome as a tank killer, his E deals on-hit damage on its own, then he builds Malady, Wit's End, and Madred's Bloodrazor for crazy fast kills. After that he'll build Rylai's Crystal Scepter and its effect slows you because of his E... You just die...
Tardir, edit one of my articles again and I will ban your ass. Seriously, there is that whole ownership tag on my articles. -_- Or do they not count for you? Thankfully Total saw sense here and undid all those revisions you made.
