Does anyone have a ballpark estimate as to how much xp I would get doing f36 small solo with prestige 35? Medium solo? Alternatively, does anyone need to do F36 and want another group member? I realize how much xp I'm "wasting" by doing it solo/small, so reminding me of the idiocy of the decision only serves to belittle my otherwise substantial self-esteem.

Go to a dg world and try to join a s/l occ, normally those last like 30 mins, probably the best you'll get outside of joining a clan or keying yourself.

You should really try joining a clan because world 77 is just terrible these days for dungeoneering.
