i never farmed, until i could easily defeat charr in the breach, to farm charr carvings for wintersday/halloween, which i do now for nicholas when i need to
i did farm in plains of jarin for certain items and pickup the gold, as i solo-ed, and even churrhir fields on HM for mes tomes, which i'd do again if i need tomes
they are mesmers after all....

and no skills is easy kill even in HM
although it'd be better if they were dervs, as those are worth more within the community, and i'd use those more, i guess (i only have 1 mesmer char)
i wasnt really a farmer, and now only farm easy stuff for nicholas, but could say charr carving farm was 1 of my first REAL ones, and also 1 i found out a few years ago, is hulking stone farm, for scorched lodestones (which i salvage into granites) and they also drop granites
thats the first few real farms i did, so i dont really have good old farming places.... these are my oldest, and they were after eotn came out (i started with proph only, before there was factions)
oh yea, i also used to farm (and sometimes still do) bows and other wood stuff in maguuma jungle and salvage them into wood (8-16 each or so) for parchments outside sardelac
