Why karma isn't as fun as she could be.
Her spells aren't rewarded if combo'd correctly (she's sort of like a mage version of rengar in a sense)
If you snare someone and Mantra Q them you just caused more damage. Rengar's Ferocity Q does more damage AND provides attack speed. I believe Karma's mantra needs more on her mantra Q. Such as a stun + radius increase on her mantra Q rather than damage. This would add skillful comboing to her mantra Q feel rewarding rather than a bonus just there.
