I have a few variations of this answer based on reality and what I imagine in my head while playing Everquest.
First Class: Magician
Favorite Class (In Reality): Warrior
Class I Would Play as a Solo Box: Necromancer
Playing EQ I love Warrior. Really I love any class without mana and (in theory) no down time ever. No mana? No problem. Just means no med breaks, no DPS slumps due to mana conservation, and no problems with weird mechanics like mana drain. Give me that Monk, Berserker, Rogue DPS party.
So my favorite class(es) in my head are Paladin and Rogue. I have this image of them in my imagination. A divine warrior, blessed by a deity they worship, able to call upon them for boons in battling what they perceive as evil or unjust. No matter the stature of the Paladin, behind their swing is a force of God. Armored up in leather, chain, and plate they are a vision of Justice and Goodness. Large shield, large sword, hammer, or flail. Just so cool.
Similarly Rogue is far more incredible in my imagination that usually in games. Talented, smart, and calculated. No matter the situation, they have it under control. Pick the lock, pick the pocket, silence the witness, silence the target. Rogues not necessarily having to be evil, but it is easier to use all those assassin type skills that way. A flowing cloak and lots of tricks. The big damaging sneak attacks. When I think of Rogue I like to think Artemis Entreri. Just so cool (too)
