Newbie Needs Help With Picking a Class

[AbstractVision]

For easiest time grouping play a Cleric/Enchanter/Rogue.

With that being said, out of those three the Cleric would probably be easiest for a new player.
Rogues need gear to be really successful and as your first toon they will be difficult to make money on to gear.
Enchanter is the most fun class I've ever played however they have a ton of responsibility in group and if you can't handle locking down and mezzing + keeping timers on mez for multiple mobs (could be upwards of 10+ pulls sometimes) then you will not find the class enjoyable.

You might also consider a druid as your first toon. They get a lot of bad rep on this server but I don't know why. Now that velious is out they are much more viable end game. You can primary heal most groups up to 50. Druids nuke harder than mages. You can CC with root/snare kiting. You can charm animals, zone specific but arguably best DPS when you can. Then the ports.. invaluable for a new player looking to explore Norrath. Ports are also good money starting at 29 you get your first four and then at 34 you can port all over the world including kunark and velious. Druids can also power level for good plat too if thats your thing.

Mages and Necros are also viable classes to start with but be careful with necro as it will make traveling certain cities more difficult.
