Yep ML credits can be bought with bounty points. Same goes for artifact credits I believe (though these still need to be levelled in PVE/RvR). CL xps can also be gained in RvR. So we just need to get out there. Which means just getting geared up to a point where we're competitive. Doesn't have to be a top template, just primary stats for your class capped, +hits boosted as much as possible and resists to a decent level (20%+ if capping isn't possible yet). Things like +casting/melee speed and cap increases are things to worry about later.
I'm thinking that with a combination of drops bought from housing, dragonsworn armour from sheeroe and crafted/SC'd gear to fill in the gaps should get us there. MY plan is to try and combine 1 or 2 "labyrinth" items with 1 or 2 dragonsworn items froms scales and then SC 1 or 2 other pieces to fill in any gaps.
Look out for things like "granite bracer", "golden bracer", anything "of the zephyr", anything "of thunder", "cyclone", "dealrach", "darkspire" or "labyrinth" going cheap as they are usually nice items for building templates around.
Id like to get Sheeroe sorted out in the next few days. Finish those quests (assuming we even need to do them in order to be eligible for dragonsworn gear, things got changed last patch and faction beyond neutral may no longer be necessary ... we need to check, someone in guild or advice channel should know).
