You would be surpised.

As the the matter of Flat AD instead of scaling, I would like to point out the damage difference on a fully-stacked ult would be roughly 6 damage. Scaling equals flat at level nine, and everything after that is extra AD you would not have otherwise.

Needs flat AD and with your line '' Darius does not need to be a glass tank to do tremendous damage'' when and who would build Darius full on AD instead of a bruiser?

You complain about my explanations being useless but you offered up nothing constructive on how to make it better. Since you want to be so critical, how about providing more information as to how I can improve?

The guide's massively incomplete, the masteries are bad, the build is a standard cookie-cutter, the explanations are useless..

Linear is right... You should take flat AD marks and flat AD quints or MS quints. I think MS quints are even better than flat AD quints, because Darius isn't that mobile... he doesn't have any natural esacpe and needs this movementspeed.

For the masteries take 21/9/0 or 9/21/0... I think 9/21/0 would be the best right now, because this gives you so much.

Also I would build a Frozen Heart (if the support or the jungler doesn't have one) instead of Atmas and I would buy a Bloodthirster.

Really bad guide, after the Atma's Impaler nerf, no one really go for this item anymore.

1. Your choice of runes is somewhat bad, Darius requires flat AD quintessence for the extra level 6 ultimate damage. If you wait that long, I think he'll be zoned out pretty hard. (Good choice for mark, but I prefer flat AD mark, because Darius is a pretty scary late-game champion)

2. Masteries: You should either add the full tree in offensive and 9 in defense or 19/11/0.

3. Build a darn Bloodthirster!!! It's such a good item for Darius after his Frozen Mallet and Maw of Malmortius.
