The only human players that give me trouble now are the ones who go Pally/MK. Due to huntresses low damage at start, and paladin's heal it can be tough to outmicro someone of equal skill in the early game. I usually breathe a sigh of relief when i see an Archmage or Bloodmage, neither lasts long against ANY ne hero. An archmage casting blizzard is a sitting duck, an archmage using WE is a perfect target for wisp detonates. Havent actually seen much bloodmage first. And, as human against NE make 2 towers early if you can, a guard tower and an arcane right next to each other, then farm them in. This will hold off early huntress attacks on your base, while you tech to rifles/priests.
