New Keystones, The ideas are great, BUT.......?
So title kind of gives you the basic idea. I tend to play healing supports, primarily Sona. But looking at these things... i'm not really seeing much that is good for my character of choice. Summon Aerie seems pretty good in theory, but also super weird/ bad during team fights. Do i extra shield my whole team if i cast the shield and they are all in range? Does this proc twice if i hit two targets with Q? But most importantly, does this mean that i have to pick and choose when to use my abilities (remember that Sona is very spam happy) so that i can get the right usage at the right time.
Then there is shit like what do you pick for characters line Jihn? Sure the little promo thing shows him using Arcane Comet, because he doesn't work well with any of the other ones, but what if the champion simply moves does the comet track? does it do AOE damage to minions? etc....
