I think Nami's heal is being reduced by Magic Resist.

I noticed this for a couple games now, but Nami's first Ebb and Flow seems to be healing allies for less than the base heal. I first saw this in an ARAM, when I went to heal a low health Mundo with a Spectre's Cowl. I didn't get the number down, so I tested this out in a bot game with a Malphite. Instead of healing him for the Rank 1 base heal of 65, he only received 42 health. Now, I understand her bounce is 15% less effective every bounce, but this is the initial cast. After some math, (0.8565 = 55.25) (55.25.76 = 41.99) (Malphite had 32 base mr, 24% damage reduction) I noticed her heals seem to be treated like a damaging spell AND a bounce.

Here's the proper format, if it helps. I don't want my fav pun maker washed up by some silly coding. :D

If Nami heals a unit, her heal is reduced by MR and by 15% (her base bounce reduction)

1. Pick Nami and play a bot game with a Malphite.
2. When Malphite has taken damage, heal him with W.
3. Notice that instead of 65, you Nami heals for 42.
4. Be sad.

Shorely I'm not the only one with this problem, but we'll sea.
