I've been thinking more about how to balance lycan without gutting the hero or sending him back to before and imo it's feral impulse that should change -- it gives too much in one ability and allows lycan to sustain through nearly anything like he's fucking dragon knight.
Wolves just need to have 5 base HP regen to start, this won't affect them at all cause they are still complete trash at level 1-2 and this won't change that. Then you can lower the feral impulse HP regen to 0/2/4/6 so that overall the regen on wolves is about the same but lycan isn't a walking fountain that can be laned anywhere. Howl should probably still cap out at 150/300 HP, 400 HP in the early nights is pretty ridiculous, especially when you're facing down a coordinated team breathing down your t2's.
I really really like the new lycan, he's a much heavier hitter (with just midas treads early game you get your 30 attack speed back and hit for nearly 150 unbuffed). He's a much better laner. His late game is signficantly better with talents. Very fun hero right now, and the night theme isn't too oppressive or forced, but it's a pretty strong boost and fits the hero's theme.
