wat ever this is the build i use and i do fine so ur choice if u wanna use it or not i dont realy care

@ThrashMaster: When you take flat MP and then a percent MP you are hurting yourself. Calculating MP takes into account the flat amount first then calculates percentage. I personally take archaic knowledge in some of my builds yet taking flat MP aswell is a waste of 9 runes.

I agree with a lot of what you said except for this. I also like the MP marks a lot since you do mostly magic damage. Cleaver, Burning agony, and sunfire capes are all magic damage and the MP marks up your damage a lot. You can go for a DPS AD build, but that isn't the direction of this build.

And on top of several things Adonikam said I dislike how your build guys is "Tanky tanky Mundo" but you only have 11 in defense masteries.

There are many problems with this build which I'd like to help you improve;
1. Instead of MP marks get ArP as you are a DPS not a mage
2. You've taken "Strength of Spirit" in the mastery tree yet Mundo has no mana?
3. Heal is a bad choice for tanks as you will have so much HP as to render it nearly useless.
4. Your description should include things like; play style, why you chose masteries/runes etc.
5. Your skill selections are not useful at all and instead of making him strong in an area you've made him weak in all areas.
Keep in mind I'm not going to down-vote, nor will I upvote until you address these points. Please don't take this personally, I am only trying to help =D

dude this is great! keep it up! :)
