Yeah. I agree with you for some points. As an initiator, the skill might not need much damage.

lvl1 -66% dmg, lvl2 -55% dmg, lvl3 -33% dmg

Since the damage has been lowered. Does he still worth to go for a refresher orb? or better go for some damage items to increase for his dmg.

And i don't think we should compare with those heroes normal skills you have mentioned with an ultimate which needs a 120-100 cool down time. Anyway, i think RP is still better than Black Hole.

Didn't get the chance to play with the new map yet. Will try it out and see how it really works. Good to have so much changes to make the game more balanced.

Just my 2 cents. 

Ursa fury swipe from 6s to 15s i think is too much. 10s ok, but to more than double the cool down is a little too much.
