Heat Blast is perhaps the Shield Tech's most important ability... but it is disappointingly unimpactful. There is little to see in terms of visual, and it makes no sound at all. Please bring some pizazz to our most used ability.

I absolutely agree. The complete lack of feedback (next to none visuals but even more importantly the total lack of sound) is staggering. I tried the Payday ability hoping for something else, but it's the same.
