Having played a Lore-Master to 50 and grandmaster jewler, I love him, can't say more. The Bow skill as a racial ability because of elf is wasted but there are plenty of other traits to use no big deal. The Lore-master can take on 3 mobs with ease at the same time (mezz one, pet takes one, and I blast and wack away on the third).
Minstral is only level 25, very powerful soloer (in the early stages of the game, don't know about highend as I'm only level 25), and constant invites to join groups. Can't have a very effective group in highend game if you don't have a healer. Not to say it can't be done but it is alot easier.
Hunter is only level 20 and very fun to play. I really need to level him further to be able to transport himself and other to various locations throughout the game. Powerful arrow damage output. Seems to be the most toon played on my server. Fun to group with other hunters and take down the mobs before they have a chance to land a blow. Kinda reminds me of the old wizzard groups in originl everquest powerful blast (using arrows instead of spells) but same results dead mob real fast.
Burgler is only level 20 also can sneak and hide very well and does alot of damage in a short time. Requires "patience" to play but rewarding and needed in high level play to start conjunctions. On my server there are not alot of burglers around.
Guardian very much needed on my server, never seems to be enough around, especially when you start doing some of the higher instances and harder quests. I keep getting tons of equipment drops for the plate wearing character. I need to roll out a guardian and give him a try however way too much to do with what I have going on now (especially with the new reputation quests with book 10).
Champian and captain not a clue what either is like never played one.
Pick one class get to know him well sometimes it is hard to jump between several toons and play the charactor to his best potential as you forget what each ability does, what all the spells do, and what works best in different situations. Once you get a player maxed you'll be suprised how easy it is to gather resources for crafting, make a set of low level equipment or jewlrey for your second toon.
