Mind Control talks about not being able to use Voice lines in regional qualifiersr

Team Liquid is one of the strongest teams in Dota 2 and has already qualified for TI8. Currently, the regional qualifiers are ongoing. Amidst all the different rules for the qualifiers, one has been highlighted by Mind Control.

It is actually weird that since Chat wheel and tipping are allowed in Majors, they are not allowed in the qualifiers leading upto the Majors. Hopefully Valve steps in to bring uniformity across their events.
