So much fail in this thread.
Spit's range is fine in my opinion. It's intended to be a ranged ability, and it's rather balanced. In fact, UB should be the model for all the other DGs to follow. He has multiple builds that he can use and he is strong without having abilities that massacre people in seconds (like erebus and sometimes oak).
I seriously hope this is a joke post, otherwise:
HAHAHAH. No. SPIT IS NOT BALANCED, just check spit and then check fireball. One is near instant cast does almost TWICE as much dmg as the other one, AND is a ability on a melee character that naturally has more dmg and health than TB.
Ub is imbalanced stupid and stale. There is only one skill build with him(and 2 variations on favor items) and the rest all suck. He's basically point and click and his abilities MASSACRE people in seconds. I can't believe you say that Erebus and Oak's skill do more damage(yes they have a few more useful skills).
Indeed I challenge every good player to play me with a decent oak/sedna and another tier I and beat me without using UB or Rook. This is impossible, the only way to counter UB is either Rook or take an UB yourself. That includes you Lethstang.
Also Erebus is rather easy to push out, UB pushes him out, a good oak does so, a good rook does so, and a good queen can push him out. That is not the problem, the real scary thing about him is, is his insane ganking ability vs squishies and more importantly his super awesome stun that allow sick sick portal grabbing lategame.
