I hope Karma's current dominance prompts Riot to rework her sooner rather than later...
Inevitable that she's going to be nerfed shortly as well.
It's a bit sad how the only way Riot's made her competitively strong is by massively over-tuning her numbers/base values. She is one of, if not the most buffed champion in the history of the game.
Don't get me wrong, I actually find her quite fun to play. She's my most played support since Season 3. The issue is that Riot's only going to nerf her to the point where she's no longer going to be worth picking over another support/mid that actually brings something unique to the table.
And I feel Karma suffers from this identity issue possibly more than any other champion in the game. She isn't defined by anything, she just happens to have some really strong numbers on some really basic abilities.
It's a shame because I really do love her design and mantra mechanic. But the old Karma, as flawed as she was, at least brought something interesting to the game despite being near impossible to balance. Riot needs to give some of that flair again. Rather than having a completely zero-risk design that is the current Karma.
Here's hoping Riot can take some far bigger risks in her design going forward to actually make her stand out.
