Question though. Will you ever pick Mana Addict for level 1? Not trying defend or criticize would-be, could-be any matchmaking here, I’m trying to point out how you’re hamstringing yourself against sniper type heroes, then proceed to complain. Nova isn’t even much of a counter to Kaelthas. In fact, Nova should be afraid of your Pyroblast. She thinks she can gank you and finish you with TT? You press 1 and survive, chip away her hp and Pyro back.
With good positioning, she won’t be able to gank you in the first place even.
