Synergy Picks in the Arena are Being Removed
Mike Donais briefly mentioned the removal of synergy picks over on reddit. This will occur in an upcoming Hearthstone patch, but not alongside the incoming balance update.
Quote from Mike Donais
This won't be removed in the Balance patch as that was added as a quick bonus patch.
It will be removed in a patch after that though. (Source)
Hey Mike thanks for the quick response! Could you please clarify, what exactly is being changed? Are you removing all the synergy picks? Changing the list of synergy cards offered? Trying a new system?
The first 2 picks will be the same as all the other picks. It is being removed. (Source)
