Will supports ever get an overhaul?

As it stands, marksmen and mages have gotten (or are getting) an overhaul in order to "improve" their kits. This is obviously an update of dated champions. One of the most controversial mage updates is of Viktor who, according to Riot, relies too much on his E and with it on cooldown marks disaster for him.

Blitzcrank is the same way in that if he misses his Q or it is on cooldown. he has to either back off or risk being killed. The same concept goes for Nami, Morgana, and a few other supports. I believe that a support update is also necessary although not as many people play support compared to mages and marksmen. This will obviously impact how far back on Riot's list the update will be. As for Viktor, in order to keep him on relying on his E they have buffed up his other abilities to make maxing them over E more desirable.

The same should go for the previously mentioned supports. People may disagree about Morgana and Nami among other supports, but Blitzcrank support is among the worst there is against a team of people who are at least level 30 (implying that level 30s know how to hide behind creeps). I know basing champion balance on the LCS isn't too reliable but if you never see a certain champion in competitive play it is almost certainly due to an inherent fault in that champion's kit. Such is the case for Blitzcrank and other supports and i'd like to see an overhaul in the near future.

TL;DR- Blitzcrank needs an overhaul and a few other supports.

This is my subjective opinion so feel free to enlighten me in the comments oh merciful summoners.
