abandon Specialist format once and for all

The vast majority of Hearthstone players (both Grandmaster and non-Grandmasters) seem to agree that specialist is a stale format that gives the competitors close to no edge. It's main aspect was to create a format that appeals to viewers by being simple and easy to understand, but based on viewer-reactions it isn't simpler than conquest in its complexity. Furthermore most viewers start to get really bored of watching the same 3-4 matchups that specialist enforces, so the format even fails in appealing to viewers.

Specialist format failed in every aspect it was supposed to improve for competitive Hearthstone and should therefore never be used as an official Hearthstone Esports format again. We need this change asap before the format can cause even more damage.
