I agree 100%. Pyrotech (Firebug) took a nerf since Beta. What was wrong with Thermal when it did not share a CD with Explosive Dart? It was not OP compared to all the other 31 pt skills. It doesnt stack, it doesnt open up potential for more damage like other 31 pt skills, so why? It is no wonder Pyro is the least played tree of the 5. My suggestions would be: Move Tier I "Improved Vents" from Bodyguard to Pyrotech and replace with "Cardio Package". It just makes more sense. Either un-link Thermal Detonators CD with Explosive Dart. or Make it AOE elemental damage.
