Are the Zereth Mortis lightsabers on a daily lockout or can i just farm the rare i want all day long and actually get the stupid things?

To the people more fluent in coomermods than me:
is it possible to tie specific Customize+ templates to specific gear pieces?

Haven't played since DT release
Anything interesting happened?
Hows the new Bozja? Am i gonna feel left behind and struggle without a group if i try to atm like in Eureka or is it less aids?
