Nice guide +1.

I have one thing to say about it: Veteran's Scar is a lot better than one point in Hardiness . In my opinion this guide is really good, but you need to add a lot more as KingPudding and zavlogs said.

I suggest you enabling the "Force to Comment" for obvious reasons (Trolls).

I agree with the above as a morde player. you should though add in an alternate build going 21/0/9 Sometimes that works really well along with having the health regen mastery instead of armor for mid lane. I do believe you need to talk about rather to use Will of the Ancients as most morde players will consider buying it over Hextech Gunblade due to the money issues. further more a section on counters would definitely help. Also to add to your con list: will be focused heavily if fed early on. I have a morde guide as well that might be able to help you a bit maybe so take a look at it if you get the chance. I might have something useful in it.

Good guide. It was very organized and neat. I think you should try and provide a few more images to make you guide look better. Go into depth about your abilities and how t use them. Talk about how to play team fights and what to do in those situations.
