So solo lane Karma is over...
According to the New PBE Update Karma can no longer function outside of botlane. While those changes seem more than appealing for support Karma, mage Karma is probably packing her bags ATM. If there was some form of compensation to make up for the removal of 2 forms of damage from her kit (RW being a huge damaging ability apart from a reliable lane sustain) the proposed changes would be more than fine. Maybe increasing the scaling on RQ so that you can benefit from it only by building AP or at least buffing W's damage a bit would be fair for all Karma players. With those changes mage Karma can only use her R offensively with her Q and her lane sustain is almost non-existent. Also, the 10% extra damage doesn't really help her that much. So she's practically even more of a Q bot than she was before.
I just don't understand why the balance team would want to decrease her viability outside of botlane, especially since she's a very healthy champion overall. Some context is necessary...
