Riot is giving us a great opportunity with the mage update.
They are ASKING for input to try to make them more interesting and unique. Instead of whining that "This mage they decided to change is perfect and shouldn't be changed," why don't you seize this opportunity to try to make them even better? Tell Riot what parts of their kits that you love and maybe even suggest some changes for the less-interesting abilities.
Vel'Koz for example: are his W and E really the best they could be? I for one think they are much less interesting than his Q and R (which he will likely keep through the mage update since they are so unique).
They are NOT completely reworking the mages they listed. They are simply trying to make them more unique/interesting than they are right now.
