LOL Well we're not sustained DPS anymore now are we? Pyro needed the rebounder. They should have come up with something better for AP.
For example: They should have given AP oil slick instead, it's a better defensive CD since it slows everyone down and takes 30% accuracy away. Not to mention that it seems more of a 'gadget-type' thing. A creative dev would have taken it further and then allowed AP to ignite the oil slick with PFT - burning all hostiles inside of it. The best skills are the ones that all fit and work together. Oil slick would at least make PFT easier to apply to more people.
Well, I played AP back when PTF required 5 stacks.... I had no free GCDs in my rotation and could only do it three times before overheating
We always had something to use, and that, in my book, is sustained. If you play something like carnage, you'll have a lot of blank times where you're just doing massacre.
Also I super agree with oil slick
