I think the main take-away here is that I'm a filthy casual who is not nearly as conversant with the current rules as I need to be to post on the topic of rules that I miss.
Nope, 2nd Edition. Three different flamer templates, plus a longer teardrop shape for Destructor/Stream of Corruption. The Thudd Gun/Venom Cannon template was the best: four 2" diameter blast templates linked together. There was also a foot-shaped template to represent the Foot of Gork for the ork Da Krunch! psychic power. The Death Wave half-circle. 1", 1 1/2", 2" and 3" radius blast templates, plus a pair of 1 1/2" radius vortex templates. Noise Marine Doom Sirens also had special templates.
Squig Catapults and buzzer squigs! Those were fun!
I don't miss the Virus Outbreak/grenades, though.
