Tyvm for ur ideas, i choose heal to be a teamplayer tank but i use ghost 2. They ap is very effective, idk if u tried my ap gear, but as i said in all my guides the ap mode is for an early game. Ill considerate ur words and ill try to make it better, tyvm for ur opinion.

Well it's a good start I guess, and I'm gonna +1 you so you can get started hopefully, but this needs a lot of changes for it to be effective. For starters, your rune choice is dismal, get rid of the armour marks and replace them with either armour pen or magic pen for Heart Zapper, also in general flat quints are almost always better than per level, so if you really wanted armour just get the 3 Greater Quintessence of Armor for the early boost and the per level turnover is like level 13 which is really late considering good per level runes turnover around 6 or 9. Turnover means when it surpassed flat stats by the way.

Also your "AP damage" build is not actually AP you just have a Wit's End and Sunfire Aegis fro magic damage. If you really want to capitalize on that, get magic penetration marks because your flat health ones are useless. Just understand what primary and secondary runes are and you should arguably never use secondary if you want to optimize your setup. For your first build you have two warmogs and a FoN built before you even get Atma's Impaler, this means you literally do zero damage all the way until late game when you finally get your atma's, this is a problem, get it sooner. And just in general, do not take Heal on mundo, he doesn't need it, and seriously don't try to tell me he does because he absolutely does not.
