How does this possibly make any sense? Viktor now can self -heal using his Cardio LC for 400 health/sec and hustle has NO COOL DOWN. The best self heal Furia can manage is 525 health OVER 3 SECONDS (so 175 health per second) and to even get there, she needs to spend 5 load out points on burning oath AND to trigger the self heal she needs to heal an ally. Make it make sense.
Suggestion: With the increased healing, hustle should have a small cooldown when using Cardio (similar to stellar wind) so that Viktor can't just break out into this heal whenever he wants.
