I play every class on here and I can say a DRUID by far does more people good or favors by a landslide than other classes.

SoW, Ports, Buffs, PL, Wolf form for faction, Pickups in FoB, Bringing gear to others, Swaping Gold for Plat as is easy for Druids to get to a Bank, strength buff for plat hogs in tunnel, food and water, inviz, lev, poison, disease cures, enduring breath, etc. etc. You name it.

Prostitution too.
