Balance Team, here's what you need to stop doing with Karma
Supercharging Karma's values I believe the buff may have came from witnessing Karma's performance during LCS 2016. Over the 3 matches that she was picked, she still struggles to make any meaningful impact by herself. The amount of times Karma dies for snaring an opponent is still disappointing and her wave clear is horrible due to the small radius of Q and players were forced to expand mantra just to clear waves using Q.
Bumping up her shield value from .8 to 1.1 will not solve any current issues she has on hand but continue to force her in to use a particular ability over the other. At .8 ratio, Karma is known to have the beefiest shield among any AP casters, there's no needed reason to amp the shield to a 1.1 ratio and provide 50% of shield value to teammates when another meaningful change you can try is to extend the duration of the shield.
A .8 shield will get the job done as efficiently compared to 1.1 shield. All these overloaded values are not a smart way to balance or improve Karma and eventually, it will come to a point where you have to tone down her values and scaling. The boards have been asking for her shield bomb, not an increased shield value.
Outside of that, people find her W provides the lowest benefit to use at the moment, which is what you should be focusing on. And looking in to how you could make Q a bit more efficient in wave clearing.
The TL;DR; supercharging her values will continue to create problems in the long run, Karma is steering off her path greatly. What Karma needs is not supercharged values, but better tools and reliable damage.
to see why a damage shield is a bad idea.
