Dynamo's ultimate does inconsistent damage

[lordcollectorttv]

When testing improved burst I found out that Dynamo's ult does 90 dmg (expected) to dummies but 53-55 dmg to champs. The amount varries between champs and can seemingly varry randomly as shown with image 2 and 3 [Ivy]. This is a strangely important bug as improved burst WORKS on the dummy but doesn't against champions meaning that the varied dmg issue is causing the base dmg to change.

This could be a resistance thing but that wouldn't explain why mystic burst doesn't work on champs who take less as mystic burst counts base dmg now instead of dmg dealt.

It's 1.5% max HP baseline damage now. This was in the previous major patch. You're getting more damage on dummies because they have way more HP.
