Karma Buff Speculation

So Riot said they have a buff planned for Karma in the next patch and I thought it'd be fun to speculate an underwhelming and overwhelming buff.

Underwhelming: Inspire mana cost reduced by 5

Overwhelming: Spirit Bond now can be cast on allies to grant them 10/20/30/40/50% Attack Speed while tethered. If tethered for the full duration, heals them a base amount. If cast with RW, the Attack Speed bonus is doubled, and the heal is now based on missing health.

What are your ideas?[slayer-pantheon-popcorn]
