It's like since the last patch there's been this consistency of 3-mage locks on a team. It's ruining the team fight balance (what little there was). I understand 2 hunters or 2 mages. Even 2 sins but 3 mages is frequently leaving 2 front liners or worse 1, with little backup besides squishies feeding a Loki or Ne Zha.
Anyone else experiencing this and finding it aggravating?
