Skarner Ult in URF

I figure that fixing bugs in URF aren't at the top of your list, but I'd like to note an odd bug I discovered while playing Skarner in URF. For the duration of his ult, the 80% CDR is no longer in effect and thus your spells go on their regular cooldown, which can be quite irritating and results in the loss of a lot of damage that could have been dealt. Like I said, it's probably not top priority to be fixing bugs for URF, but I'm just throwing it out there.
