Beware: dorky gaming post ahead.
I worked my first toon up to 20th level and became increasingly irritated. Hunters are useless against multiple mobs, and frustrating in fellowships because all the mobs will gallop past the champs and guards to get to Mr. Feeble, the hunter. This is NO FUN, so I started a second guy with the idea that I would go in a completely opposite direction.
So I rolled up a dwarf minstrel, and the game is fun again. Minstrels are LOTRO's healing class, but most of their low-level heals also do damage. I realized how much better this class was when I got jumped by three mobs, all at or above my level, and after a somewhat protracted battle found my toon standing over their bodies with most of my MP left. Cool.
But the best part was completely unexpected. Minstrels are a necessity in fellowship quests, and there seems to be a dearth of them at all levels. So I can mosey out to whatever site I want to work on and it's almost guaranteed that there's a group of tanks (and a couple of fifth-wheel hunters) looking for a minstrel. It's like being the easy girl in high school: sure, you get a lot of attention, and afterwards you feel sorta used...but it gets you LOTS of experience.
