1) It's 40%, not 60%.

2) He needs to be level 16 or higher to output 100% of received damage.

3) The effect has a 3 second countdown.

4) There is no guaranteeing that Hannibal will be able to use those 2 dashes since anyone can mount strife.

But yeah. I at least agree with you on the range of the effect. 500-radius circle seems a bit overkill (for comparison's sake, Karthus' defile is a 425-radius circle).
