Same problem!

You can flush Crew Skills in WC now, they just dont required.... Modules? Drops from flashpoints. Armor? Only as outfit. Weapon? Well only weapon is normal... for now. SWTOR became too much casual. Hah, i so miss classic SWTOR, with its: advensed class at lvl 10, with perks sheet, with unic crew members(with their unic crew bonuses), without that damned light/dark switcher.

12. How many companions can I send out at once? Your current level will determine how many companions you can send on a crew skill task at any given time. Here is the ‘max deployable’ list according to character level: [Level 10] – 1 [Level 15] – 2 [Level 25] – 3 [Level 40] – 4 [Level 48] – 5
