Karma shield nerf?
E - Defiance (Mantra) BUGFIX Fixed a bug where allied champions were granted the inspire portion of the shield, instead of half of the defiance damage
This description is really unclear. Is this referring to a bug that only happens sometimes, or one that happens every time the ability is cast? Normally, the patch notes will include the world "sometimes" if they are talking about an intermittent bug.
If this is an always-bug (e.g. it always behaves the "bugged" way, and effectively the tooltip is wrong), then this is a massive stealth-nerf to Karma's RE, making it about half as effective as previously.
I'm nowhere near observant enough to note what value is normally applied to allies when using RE (since the values of shields aren't shown anyway), so there's no real way to know which one it is.
