3 supports are getting reworked

according to champion gg there are 28 champions who could be played as support. taking away the champions with heals, shields or the tanks we are left with 4 mages sure there are more mages like lux or zilean but these are the champions whose kit is only about damage 3 of them are getting reworked. i hope this isnt a way to take them away from the bot lane. we already have problems to find someone to go bot and these are some unusual picks to use when we are tired to be a grab machine (blitz, tresh, nauti, leona....) or a warmog. sure zyra needs to be reworked but brand and velkoz didnt need anything. velkoz is a new champion and brand feels really unique with his passive. did they really need a rework more than kartus for example? or are you trying to leave us with even less support players'
