I'm glad to see that I'm not alone in thinking the current limitations of UL are very restrictive. As much as I love using thunderbolt, I only get to use it once every 5 minutes and essentially prevents me from using Tourbillion, Gates of Hades, or whatever utility spell becomes available with UL. In fact, I find it funny that the spells themselves have a recast timer of their own. I originally came into the BLU forum to post a suggestion about UL being like Tabula Rasa and giving us free use of the spells and still be restricted by the spells' cooldown while still being allowed to use those spells for say 2-3 minutes. However, the strategem idea is actually pretty cool too.

Also, total side thought -- wouldn't Citadel Buster be an awesome UL spell?
