what i normally do is send in the huntresses and demon hunter, then then once the other team is busy fighting them i ambush them with the archers i had hideing between the trees, since they dont get hurt cos 1. they cannot be hit by alot of meele unts (trees are covering them) and 2. the other teams units are stuck in meele with my other units
and i allways hunt for outlaws at night with a small group of units, archers normally but it depends on the hero i have, and then hide whenever anouther play comes past.
I allways storm bases at night too, but then i use my powerfull meele units like 1337 said, cos when i hit a base i DONT hit it if i cannot win, that would be pointless killings and also tick of the other player, best not to do that.
im abit of a whore really, alot of ppl say that its cheap hideing archers inwait in trees and stuff, but i say if u can hide at night and do sneck hits on ppl, DO IT.
