Summon Aery AKA diet comet
Since they announced the new runes I can say that the only one I was disappointed by was Summon Aery. There's nothing unique about it. It deals some damage or gives a small shield and both scale? It's like a diet comet with a small shield. It became really popular when they were released but the fact that people took summon Aery over the full damage rune? They're too similar.
I think there's potential for it to be a better rune. Specifically one for supports to utilize. The one idea I had was that the rune should add additional effects or just buff a spell that's casted on allies. Each type of buff would become slightly stronger. So shields and heals could either add some armor and mr, get buffed or give some mana back. Speed boosts could be buffed by a small percent, or something. I haven't thought it throught long enough to balance it for every champion but it's just an idea. I just really don't like how creative Summon Aery isn't. Any thoughts on Summon Aery or what it could be?
