I think geting triforce and frozen mallet in the same built is big waste.
With Atmas on, Mallet gives you 34 bonus dmg 700 hp and 40% slow, now Warmogs gives you 25 bonus dmg and 1270 hp, now is the slightly better slow than in triforce and 9 ad is worth 570 Hp 40 hp/5sec and 250 gold? Nah. U have slow in triforce and with it you are already fast enough to catch and "make a run like in soup" anybody, you have also Q dash with toss and E slow.

You are off to a great start. I hope you can continue to add information to this because there is more to know about any champion than could ever be put into a guide so please continue to add information and work out the bugs. The build itself looks good and your information is fairly accurate so keep up the work...
