A very small thing, yet such a big thing for us that role support!
There isn't much that comes with this request, but during my struggles of being a support, the scenario where getting hit with low hp so I don't have time to hit back, only to end results with the person attacking you ending up dead, your team gets a kill, maybe some assists for others.. Except for the support that got hit with low hp.
I'm not sure if it has been discussed, but I feel being hit during fights can be just as important as giving damage itself since you're taking the time of an enemy who could be attacking someone more important. So I ask, will there ever be a day where League of Legends applies assists for getting hit?
