Actually they can fix it very easily...reset the map on Tuesday like they use to!
It used to be the same map as LWO, so you had a week to win it, then it would reset. LWOH has ruined that. With TT having to be a separate arena, we can either have a TT map that stays the same for months on end, or a TT map that only lasts 24 hours so no one can ever win it. Either way is bad.
LWOH is yet another example of a decent idea that had bad unintended consequences.
