If we get a support update
I want to see a wider gap wedged between their functions and a bigger emphasis on niche power as well as some gameplay issues addressed
as it is there's a good amount of overlap between both traditional 'enchanter' supports
and some of the tank supports
. They have a lot of the same general purpose, so one of them usually ends up crowding out the others when strong, and a good chunk of them also have problems with low counterplay, which became most egregious when they were strong enough to dominate solo lanes.
Supports that stand out to me are
. I think
is an in-between case; she has a little too much in common with other enchanters, but she has the really interesting characteristics of a support that greatly benefits on-hit style champions, that could easily be emphasized a little more in tandem with being a strong anti-assassin or anti-stealth champion.
Soraka needs to be something other than a raw healslut. It makes her very lopsided; if her heal is too strong she's top tier, otherwise she sucks. Janna can be the go-to enchanter for pure defense/anti-diver stuff; she has some gameplay issues but her niche is well-defined. Sona probably needs larger than a class update? Karma, I don't really know what to do with her since her community is so split on her. Zilean is kind of old-school and probably does warrant an update, too, but again, I think the scope of it would be beyond a class update.
Tahm and Braum also have similarity issues too; they even have vaguely similar names. Both of them have a slow, a conditional stun, and an ability that directly protects their teammate. Possibly, push a little more focus towards making Tahm offense-oriented again since you gutted the shit out of his fighting power a while ago, and let Braum be the ultimate defense guy.
Also try to make some of these guys playable in other lanes/the jungle. Once counterplay issues to some of these champs get addressed, there should be no reason to refuse them the right to take a solo lane's gold income.
