CDR isn't a stat Rumble is especially interested in even on live, and I don't think he really needs to operate on building CDR. Technically, scaling on fewer stats is a buff overall, since you scale harder with the stats that do benefit you, though I'm pushing Rumble to invest more in resists on top of health and AP, in order to better survive his shorter range.
