As it says in a blue post on mmo-champion Thunderstorm and typhoon might be getting its knockback removed by getting a glyph . This is the bluepost saying *Glyphs to remove knockback effects on some abilities
We are considering glyphs that will allow players to remove the knockback from Typhoon, Thunderstorm and Blast Wave in return for some other benefit, such as more damage or a cooldown reduction. You could then use these glyphs when raiding and not make the tanks mad.

Well anyway just keeping you guys up to date if it does get removed then what are we going to do for cc?
