The first thing you want to do is read the beginner guides on the wiki. Great help there for new players.
Things to know:
Everquest is a lot different than other mmos. You will have to depend on other players. You will die and get frustrated. But believe me, we are still playing this game.
Classes for newbies (in my opnion):
(if you want to dps)
-rogue
-monk
(if you want to tank (preferably not a good newbie choice since most tanks are gear dependent)
-paladin
(If you want to heal)
-cleric
-druid
(if you want to be support/kind of everything)
-druid
-bard
(if you want mainly cast spells and have a pet!
[You must be logged in to view images. Log in or Register.])(both have pets are good for soloing)
-enchanter
-magician
-necromancer
Its all up to you tho. Tbh just pick a class you like and just roll with it. There are plenty of guides on the wiki and players are extremely helpful with new players.
You should definitely be playing on green if you want to be able to group with other players at a low level. The green server is currently on vanilla states and on November, the kunark expansion will go live. So, now's the perfect chance to start playing!
If you ever need help, send me a tell in game (Knifeman)
Good luck and see in Norrath!
