@Riot, Can Karma get a little bit of love?

I've been playing ever since Season 3, and lately I've been noticing...I don't know if it's me or but...she feels very underwhelmed in many occasions and I can't seem to understand her anymore. Many champs have changed, runes and items as well, yet I feel like Karma is not adapting well with these changes and that she feels like she's been left behind. Her W doesn't seem to be very reliable these days, and less her R+W with the whole fact that can be easily burst down and it takes too long for her to survive a sticky situation with R+W+E. Also, I know it's asking a lot but...the R+E Bomb effect from a long time ago was very reliable in certain sticky situations. Her only reliable damage now is Q...

What am I'm trying to say is that, is there a way for to feel more fun and understandable in the battlefield? Like I said, I don't if it's me or her.
