All casters have access to Blizzard 2 which is a PBAoE snare at a 2.0s cast. Personally I don't think the increase rate of xp and marks should be given to solo, duo or quadro queue. It will just funnel all the players into that comp and promote botting even more. Though I still don't get why Melee have to be restrained towards only depending on a PvP Skill to apply Heavy (Weapon Throw). It'd rather they have a skill which will cause Heavy and Weapon throw being a Ranged bind.
