Minimum T1: 5 active virtues must be 72+
Minimum Challenge T2+: 5 active virtues must be capped (currently 75)
Recommended: Cap as many virtues as possible for passive bonuses. It's better to cap a single virtue at a time because the bonuses really accelerate from 60+
How we'll help: Occasional deed runs, e.g. Moria instances Saturday afternoons
Minimum T1: 92 trait points
Minimum Challenge T2+: Capped (currently 95)
How we'll help: Big Battle runs on request for promotion points, or to progress the epic (e.g. Gondor big battles)
Minimum T1: 7 legacies, capped crystals (currently 71) and legacies at least at 80 for each LI (current cap is 83)
Minimum Challenge T2+: 7 legacies, capped crystals (currently 71) and legacies (currently 83)
How we'll help: weekly LI advancement runs. Also see the LI Guide page.
Minimum T1: Player is in full 426 teal gear, with class / role appropriate stats. Highly recommended that player attempts to get teal 428+ gear from Stairs T2+ 6-man runs (at least a few pieces) to make things a bit easier.
Minimum Challenge T2+: Expectation is that player is in at least full T1 gear (teal 426 currently) with at least two pieces being for their appropriate class set bonus. Also require class / role appropriate stats.
Raid leads may request screenshots to validate build.
What do we mean by "class / role appropriate stats"? See LOTRO HQ for more information on what the broad consensus is here, though by no means is that site the ultimate end all, be all for what is viable. Ask any of the officers in-game if you have questions!
How we'll help: Not a straightforward path here, but just ask in-game if you need a particular run, a questing buddy, etc.
