[Warlock][Demonology]Wild Imps Fel Firebolt vs haste

[Ph3n0]

WoW Freakz spell link: https://www.wow-freakz.com/spells.php?spell=104318&&name=fel-firebolt
Character name:
Bug description: Wild Imp's Fel Firebolt benefits too much from haste than it should.For example it has a cast time of 2/(1+haste) seconds, the same as (for the sake of example) Shadowbolt. NOTE: Shadowbolt's cast time works fine.
So let's do a little race with a wild imp:
At 0 haste, we both have the same cast time.
At 11% haste, i am visibly being left behind.
At 20% haste, the wild imp outpaces me easily.
Because of this and This, a demo lock can rarely reach 9 active wild imps in fights with very low haste.

Hello

After testing by myself, i've got the same result :

my haste : 27
Calcul : 2/(1+0.27) = 1.57
Si imps should cast at 1.5 or 1.6sec of duration.

But in game i measure 1.2sec.

Best regards
