Snake Trap - clunky and inefective!

Any one else feel that snake trap isnt very helpful. The snakes are easily killed with aoe and their dps is extremely weak.

Why not make a spike trap that is covered in poison? It would certainly look awesome and not be so easily avoided by like an aoe.
Snakes are somewhat useful in PvE. They count as extra "players", so they're useful for when damage is split.
