Starting a Captain

[elithrar]

Hi all. Looking to start a Captain and am hoping to get some updated advice. I've dug through what looks like Helm's Deep relevant info on the Cappy, but still have a few questions:

• Red line for my trait build? Red/yellow mix or red/blue mix for solo levelling? Seems the self-heals would be the most useful here.
• I understand Captain DPS to be about "80%" of a Champ/Burg in instances: is that about right? Obv. Cappy's bring additional group utility beyond that.
• Soloing elites, scenarios and/or 3 mans when levelling: doable? Red or yellow?
• Herald or Archer? (does it matter?)
• Tanking and/or healing in groups during levelling: more than viable? Need an alternate set of gear to do well?
• Crafting: Armourer or Armsman? Is having "okay" armor and a "great" crafted weapon better than great armor and an "okay" weapon?
• Any other advice?

Thanks!
