my fav - sticking to humans. this is the most "dretchy" in my opinion. make it like the basilisk except opposite, if you see what i am saying. use wallwalk or another key to toggle on and off. make it so a human could jump to get the dretch off, and the hit will count as a leg or chest shot, so there was some leeway. It would be awesome if multiple dretches could attack 1 person, especially a battlesuit. what would be cooler than a swarm of dretches leeching on to a battlesuit trying to rambo the alien base?
for that matter, how about the advanced dretch can split into multiple tiny dretches? Have like a "bundle" of 3+, and each counts for 1/3 damage and hp. all controlled by one player.
on second thought, I have no idea what benefits this would add. i just like swarms of flesh eating creatures.
one way or the other, i want to stick to a battlesuit when I jump at their heads. i'm not asking for much.
if nobody likes that, then give the dretch an appendage that shoots pulses of energy... and kills things really fast... we could call it a pulse... rifle... just kidding. but seriously, a pulse rifle dretch. no, no, i'm kidding... PULSE RIFLE!!
