Banshees: Don't know if it blocks exhaust or ignite. Same would be with this spell.

Trynds ult: Once per game, he is unlucky, I'd say. But you know what? A good LeBlanc combo comes from bush and takes something like 0.8 seconds, and deals 100% of Trynda's health as damage. Because Trynda's ult takes 0.5 seconds to activate, he'd have to react within 0.3 seconds in order to not die. Isn't this godmoding too?

And really... You don't require to take it. It leaves you with only one summoner spell for the rest of the game. That alone is enough to balance it. Actually, Flash has something like the same problem at the moment. Everyone takes flash. Then I come with my Exhaust+Ignite, and get first blood lane after lane in top. With this spell, it would even be worse, because using it in lane is a waste. You can kill your enemy once, but I've seen very often someone giving away first blood in top, then come back and win his lane. I have even seen my enemy come to a killing spree, NOT making mistakes (maybe she could've run more, but she was ahead of me, so I understand she didn't), and I've still won my lane.

As you can read above, yes, you can learn it's use. Using it as soon as you see an enemy is a waste, waiting with using it and finding out there is a nexus destroyed before you use it even more. You need to be tactical with it. It's like not using an offensive flash, then noticing your TF just got level six and makes the kill with his ult (and find out you didn't need your flash anyways), and twenty seconds later, you get ganked, and manage to escape thanks to that flash you saved. Always think: Should I use it now, or will there most likely be a better moment to use it?

And, as I said numerous times, this spell is MEANT to counter people who are unkillable. They'll maybe still be unkillable, but at least you have free space until they respawn. The exact use of this spell.

To avoid noobs using this wrong, I'd say, make it at available at level 12, like Flash. Pros know how to use it, so there is nothing wrong with it. And what you descibe there is indeed how I meant the use.
