It is now 2016, is there any root for G900A?

Is knox part of the reason I can't root G900A? I realize the bootloader is locked by default. What can I do to get root? I am on 5.0.

There's a rooted OC1 ROM ([Rooted OR Stock] Update Procedure For Lolli… | AT&T Samsung Galaxy Note 3 | XDA Forums), or you can root 4.4.2 (you have to revert to 4.4.2 to install the OC1 ROM anyway - and if you want Xposed working, you can't get it working on OC1 odexed).
