Let's talk about soraka

HI guys, I'm a Soraka main that have been playing now and then since season 3. I have seen many states, from the top lane tank Soraka to the ardent abuser one.

This pre-season Soraka feel very unsatisfying to be played.

The reasons I have to experience the game this way are:

Her main role is to be a form of sustainable " post damage mitigator" and I feel she can't really do that on the situations she should based on too much damage happening on a short amount of space (either from 1 attack or skill alone or by multiple attacks).

Ex: For example, we are 40 min in, enemy jhin decides to use the last hit of his ult on my recently 60% hp vayne... vayne dies.

Enemy nidalee lands a spear on my adc... ADC dies.

Enemy ezreal lands a Q on my adc, my adc dies.

Leona jumps on my adc, my adc dies.

Etc.

I feel that Soraka need a way to reduce a % of damage on at least one of her targets to give time for her to heal him/her properly. Maybe a passive that starts at 0% damage delaying to a selected ally but that increases as you land starcalls and use her W right away (made this way to prevent abuses on top lane or mid and offer interaction).

The passive could simply work like death dance's passive and be either an area around her or an effect to a selected target.

A well played Soraka could delay, let's say, 20% of the damage the ally is receiving through 2 seconds. I think this would give her enough time to heal at least once more before the player death.

Well that's it guys, thank you!
