Karma is as abundant as air, and as useless as the Kardashians.
A few ideas from other games:
Instant Adventures(rift) — Queue up and be ported to a location in the open world where you are completing public quests(sure dynamic events) with many people that have queued for the same. Other adventurers will not see or be able to participate unless they have queued.
Skirmishes (WoW scenarioes, neverwinter skirmishes) — Queue up for quick 15 minute battles. Storm a keep, defend a keep, defend XYZ, blah blah. Quick 5 man group battles for decent reward/xp/etc.
Solo skirmishes — Same as above, but solo.
Chronicles (Rift) — Heavy story related 1 or 2 man dungeons. A lot of story and lore, takes 20-30 or 45 mins to complete.
BAMS (Tera) — Big kitten Monsters. Open world mobs that require coordination of a group of people. The mob hits like a truck, has unique abilities, and takes more than 20 seconds of zerging(thinking 5-10 minutes). Southsun is a perfect locale for this. Monster Hunting!
Replay story content — self explainatory.
