If you have only one or two 2* items in your loadout, then un-flag that loadout for PvP. Make a loadout of only your 1* or less items that is flagged for PvP and stay in T1 PvP until you have at least a gained T2 access in PvE (at least).
Seriously you will have a better time playing T1 lockdown in a full Proto loadout then you will taking your Proto armor and shiny new Calibur into T2 PvP Lockdown.
