I'm actually still kinda split on whether or not to keep the Danger Zone bonus. If you check the history on this post, I originally did have a 50% damage amplifier on Flamespitter at 50 Heat and above, but I removed it afterwards. My main reasoning for this is that the Danger Zone exists on current Rumble in order to push him towards stacking up Heat, since he could otherwise enter trades at 0 Heat, use every ability, retreat and repeat, which would allow him to effectively bully his opponent without putting himself at much risk. With this model for Heat, though, Rumble's damage is no longer contingent on basic ability usage, and he's much more vulnerable overall due to his lower range, so he'd have a much more natural incentive to build up a lot of Heat very quickly. I also think damage amplifiers in general tend to not give the greatest feedback (you're doing the exact same thing, only better), which is why I try to avoid them.

As for ranking up his abilities, you're probably right that his W is the only ability that scales up majorly in lane. I'm okay with a champion having a leveling path that's more straightforward than the others, but the base shield probably also ramps up a little too hard for a spammable effect, so I'll make some adjustments.

As for CDR impacting on Rumble's kit, my main argument against this is that Rumble isn't a champion who's innately meant to scale well with CDR, and not every champion needs to scale well with the stat. If he's a champion with no cooldowns, the last thing you should be considering is ways to reduce cooldowns. As for CDR affecting Heat decay, specifically, I wouldn't want to go with that because the above model for Heat decay is specifically constructed around his ability durations, and any amount of CDR would be liable to lead to some abuse (e.g. Heat decaying fully or partially even as you're chaining shields and/or slows). Because the overheat effect is also tied to Heat decay, having CDR impact on it would shorten Rumble's windows of vulnerability overall, and I'd rather he have consistent points of weakness so that he can be made stronger in other places.
