dude... you musnt know any thing about night elf....
heres a counter for each hero
priestess, searing arrow, does extra damage wich should cancel out the life steal for the target
keeper, entangling roots, ghoul cant attack and it also takes damage over time so ghoul is 100% paralyzed
demon hunter, immolation draining 1 mana a second dealing 10 damage a second (lvl1) that would cancel out the ghouls life steal +the demon hunters already high attack damage, gg ghouls
warden, fan of knives, deals 75 damage too all surronding enemy units, that would cancel out the life steal + extra damage per use, also the warden has high attack damage
ok so yeah, try that ghoul thing against me? we will see who the victor is...
