TB will hit PTS in August (probably last day
) with Story and HM. NiM TB will not be out in September or October
NiM EC (been waiting so much for this
) will hit around the same time as Story/HM TB.
The new gear will be level 63, so Columi-56, Rakata-58, Campaign-61. The gear difference will be the same as Columi to Rakata, a decent improvement, but not enough to allow people to solo Story EV/KP or Lost Island.
