Absolutely. The initial cast of sleep lasts for far too long if it is not interrupted. 20 seconds is an eternity in a PVP match, and is more than enough time for the caster to cap a tomelith/use Cometeor/whatever. Purify used to be used almost exclusively for Sleep, and so it wasn't as big of an issue, but now that we have way more things we need to Purify, Sleep is once again the worst thing in PVP.
(God damn they need to increase the character limit.)
