Karma should NOT have been nerfed for Athene's
wasn't even given a significant buff (I would argue it wasn't buffed at all and quite possibly nerfed, at least for mid lane which is when
most often built it). The biggest draw to it honestly was that it had 20% CD reduction, which allowed you to build it to max CDR quickly. This was great on
because of the synergy with her mantra/passive, and it allowed her to use it as a substitute for
mid lane.
Giving it the extra AP wasn't a huge buff when it lost the CDR.
getting her shield nerfed AGAIN to "compensate" was not necessary at all, and she now has the lowest win rate of all the supports. Also,
is arguably a better user of
, and she was left untouched, despite having one of the highest win rates of all supports, both before and after the change.
Let me say this as well -
has had her shielding consistently nerfed. Part of this is the addition of % healing shielding power (
have seen their healing/shielding nerfed as well), but it's mostly attributed to the Patch 5.10 changes to her R-E/R-W and subsequent buffs to R-E.
No one ASKED to give
a gigantic shield. We wanted to KEEP the shield bomb; all she needed at the time were the buffs to her mantra CD reduction at later levels.
was already a big nerf to her and they still decided to nerf her because of
of these made for 30% (35% with masteries) CDR very early. This is powerful on a champ with strong CC on a Q skillshot. It also allowed for some healing on Morgana and extra healing on Bard.
(215 AP build)
and the jungling items (but only in the jungle) are the only other items that increase % base mana regen.
