OK, I both love and hate it now.
I used to build it all the time on ADCs. Only reason I didnt sometimes was I would get sick of some noob griping at me Im building wrong.... I swear atleast 5 games were thrown just so some assclown could blame me for building ER... Anyway.
Now I can rush it, still get crit stat, which is important, and the mana sustain.
Here is the problem, the MAIN champ I would build it on was 
Urgot dosnt need crit. Now Im buying a stat I dont need. I usualy build
into
and get a
.
This is good because the active works on his Q. Urgot is an AD caster type. Hes closer to Talon or Rengar in that most of his damage comes from abilities, ranther than repeated auto attacks.
Here is the thing, the Muramana (final form) active puts a huge dent in your mana, and the
helped keep his mana up. NOW its mana sustain is tied to crits, and I dont need crit on urgot, but the ER isnt very good without other crit.
I always got my cooldown from
and ER, stoping at 30% as that was good enough. Now the ER is kinda trash, I have to "get lucky" to get mana back, making my Urgot game as a whole much less viable... and believe me thats pretty sad as he isnt exactly top tier. I play him mainly in top lane, and there is some really broken shit up there, and having my mana sustain screwed up really hurts.
So I like it for when Im playing Ashe bot lane, but hate it for the only champ I played top. Id have rather it been left alone as it just "helps" me on one champ, and has me looking for a new top on another.
So final conclusion,
is kind of a mess now.
Another thing, Im pretty much certain that this patch was the result of a bunch of AD/Marksman biased anti mage bigots who somehow got away with creating a patch that shows how much they love
. Two champs no one wants to play against, now in every game, massivly buffed from this AD-centric patch.
That said, Urgot a champ that can only do physical damage, made worse in every way this patch because he uses mana unlike Yas and Tryn.
