BlitzCrank's 30 Second Cooldown Ult. Let's talk about that.
At the very least Riot should consider increasing it just a bit. Most supports have 90 second cool-down's at rank 1 on their ultimate's and take way more skill/knowledge/mechanics/ and just general overall experience. It's obvious math but I'll say it anyway and use a basic comparison. Leona's Ult is up every 90 Seconds while blitzcranks is up every 30. That's 3 times as much pressure. That's every single teamfight and every single skirmish post 6. No other champion has that in the entire game. You may want to use Nidalee, Jayce and Elise as Exceptions but comparable to supports their "summoners" require a lot more knowhow/work on how to fully utilize their abilities I feel that this is the most unhealthy part of his kit and one of the best way's to give a opposing players a window of opportunity.
I don't think it's too much to ask of blitz players to show what they're made of/raise the bar a little bit. This would be a perfect way to separate the good, the bad, and the great.
