#3 is not really an option if it is not efficient, which is potentially the problem. Having the option to do something but it being completely pointless is not really an option at all. Just like in WoW you can level up only killing mobs never questing or running a dungeon... but it would be stupid.
The devs need to remember people raged in 1.0 about there being no group based xping. And I do not think dungeon raiding and random battles in the field with insta-pugs will cut it.
This is the only major issue I see from my limited knowledge of Alpha, still waiting for my invite to actually test it out myself. Group based XP outside questing and dungeons should still be > Solo quest XP. I know they are making the game sorta like WoW but the forced Solo questing and party only in instance mentality is the BIGGEST NEGATIVE WOW HAS.
SE needs to ballance every method. In the end group XP must be good enough people prefer it over solo or solo will be the prefered choice. Solo takes 1 person, group takes 2+ if solo = group everyone will just solo.
1) Group based xp chaining on hardermobs in the world should give really good xp.
2) Solo questing should progress you at a decent rate.
3) Fate should progress you at a decent rate
4) Dungeons should progres at a decent rate.
Have to remember there are a Lot and I mean a LOT of people who hate questing.
