If and when the Support changes come, here are a few thoughts from someone who plays Supports.

Please buff Taric's heal. Make it so that it costs less mana... or so that it heals based on 20% of his health and 40% of his AP per rank leading to at most 60% of his health and 120% of his AP in a heal. His heal is very situational and takes forever to reuse. Don't get me wrong, I love his change, makes him just as hard to learn and use as he once was but his heal feels like it does less than it use to and for a greater cost, none the less.
