ADDITIONAL INFORMATION ON RAMBOING FOR THE EARLY LANE!
-In general, you want a skill that either makes them come to you, makes you come to them, or makes them stay put.
-Tower? SO WHAT?! If that kill is almost a guaranteed thing, who cares if you die after? You got the kill!
-Enemy weak? Try to make sure that the rate for successfully killing is at least 50%! Works better if you have a 'get outta dodge' skill!
-Tanks are pretty much designed for this. Yes, even Kaguya.
-If you take 100 damage to deal 60 damage in the early lane, then you won that fight. You'll regen faster than him! Keep up the annoyance!
-If you do something when you hit or get hit, attack those creeps when melee heroes are near! Forget last hitting, this is about messing up their day now! This'll teach 'em to last hit!
-If they are faster than you while you chase them, turn around and walk for a bit and then turn around again. You ain't catching up and they'll most likely turn around to get back to the creeps and they won't expect you to turn around again.
