I have sent several 'helps' to bioware but not getting the right answer as to why I can not complete the quest

Anyone Jedi Knights do the 'The Valiant' mission, if so how do you enter? Iam having great difficulty entering the ship even when it says for 'Jedi Knight class' very strange.

I am currently a Lvl 50 Guardian, where else can I find lvl 50 robes at besides Coruscant Legacy Vendors? I am currently outfitted with PVP War leader Gear, I want to use gear for PVE when I tank on missions

I am currently a lvl 11 Sage, Where can I find a double bladed lightsaber. All my new moves require the use of a dual lightsaber, I cannot find a vendor. Currently on Carrick Station and Coruscant H E L P!
