[Suggestion] Slow & Arcane Blast

I was once told that since there aren't any more suggestion forums, that you should post in the forum your suggest most relates to, that's why i'm posting here. If i'm not supposed to, then i'm sorry, but the General Discussion is just too gloomy with all the Blizz-hate and /perma-camp'ers

So my suggestion isn't really a suggestion, just a request from Blizzard. I started questing again on this mage (mainly just so i could get to outlands) as arcane, i love arcane, it's my favorite spec, but when i was using arcane blast, i would notice that the mob would get some good distance towards me before the slow effect would kick in from my Nether Vortex talent.

TL:DR My request is this: With all the changes blizz is doing to arcane mages, can you make it so that the slow application is just a tad bit quicker on the draw when i first use arcane blast against a mob?
This is a bit of a bug, actually. Nether vortex applied slow properly, but the problem is that arcane blast has 5 yards more range than slow does. And because vortex is basically counting it as you casting slow, it won't go through until the mob hits slow's range.

The current workaround for this is to glyph slow, so that their ranges are the same.
