I get why he needs it, but...
Darius's Healing seems a bit too much/easy to reach high potential.
It would probably be fine if they reduced the frequency of it or increased its requirements, but the CD is 9 / 8 / 7 / 6 / 5, on a champion that rushes
99% of the time and only 3 targets seems a little bit too much.
So he's got a potentially 36% missing HP heal on a 7.2 / 6.4 / 5.6 / 4.8 / 4.0 second CD...
It just seems a little ridiculous that a darious can heal at least twice in an average fight, and as in my last game, for 1.1k health through grievous wounds the 2nd time... (to save you the time on the math, he had 4105 max health, and landed a 3 man Q at 67 health)
If the CD was increased to a flat say 7 or 8 seconds, or he was given 7% per champion hit, it might not be such a ridiculous degree of sustain. Hell even Nasus w/ warlords, high stacks, and BT can't heal for that much.
