Karma's e
Karma's e is very simple, it's an instanteous shield that costs a fixed amount of mana at any level. It's common for me to hear people saying that karma's kit is just too much spam and that she takes no skill to opperate. And to be quite frank she really doesn't. As long as you can manage to hit her q (which takes some precision) there really is no other aspect to her that requires you to actively think about what you should do. It's simple, you see somebody is going to take damage? Shield them. If you see somebody is being chased root them with your w.
But what if we were to throw out karma's shield all together?
What if Instead of karma having her decaying speed boost and shield there was a toggle on her her shield? This ability would allow karma to create a shield starting with a very low mana cost and small shield but over time the spell drawed increased in size, increased movement speed, and dramaticly increased mana cost?
Take kassadin's ultimate for example, over spell use it has a longer mana cost which means that not only will it be more effective but you have to be also have to be more careful how you use it.
My idea for her mantra is that it's the same concept but instead it effects all teammates around her aswell.
