Just get the Recruit MK-2 gear-set from the PvP-terminal at the fleet. This is enough for every HM Flashpoint except Lost Island, and also good for Eternity Vault and Karagga's Palace -operations in Story Mode. Grinding Daily-commendations for Armorings isn't even productive anymore, just drop the idea of doing it.
I am very very astonished about this recruit armor.
All dailies are well done with yor fresh 50 gear - blue and even green. Dailies get you purple 50 and 51 mods Tionese grade, which you can get from HM Flashs Tier1.
Recruit MK2 are slightly worse then Columi - which is the goal of HM Flash run... there's no sense then in HM Tier1 - you got already that level of gear that HM Tier1 can give you...
May be BW think fresh 50 must go streight to the HM Tier2 or even Operations?
Or they think gamers to be too dull to play HM Flashes not overgeared!?
