@BLVD69Conversely, I'm not particularly fussed nor significantly interested. That's not to say it won't be good! Just that what I've seen just seems like refinement or just making the sound louder... It's another level of customization (which is probably desirable and genuinely wanted in this case) like the clothing which consume resources that could've been used elsewhere.
Ultimately, I don't mind and appreciate the initial signs of innovation. But, unrelated to customization, the damage system still holds back Heat for me massively and it would be much more desirable without it, at least to me.
