Followed your tips and used your runes and build got a 22/2/12 match
Nice guide :)

Yes, i see what you mean. But it all really depends on how your game plans out. I find that with only the Trinity Force i deal quite alot of damage, i do not find it necessary to go Hextech straight after the FoN, even though you deal crazy amounts of more damage. you will still get kills and everything else soo i personally choose see have kind of feats my teammates brings to the table, if we are lacking damage, I might even go hextech before the FoN.

FoN and then a Thorn mail maybe get a rylais or a gunblade then a thornmail would be better but nice build
