My favorite classes in western RPGs always have summons or auras. Ranged vs. melee vs. spells doesn't really matter as long as I can approach a mob, summon my guys and set up my buffs/debuffs, then clean house. Barbarian, Druid, and Necromancer were my three favorite Diablo II classes and I really enjoy all four classes in TL2 because all of those have summon AND aura options (except for the D2 Barbarian, whose war shouts and look I love).
I should also mention: I overwhelmingly prefer tribal/shamanistic looks over gothic/medieval looks. I avoid knight/paladin/holy characters in general as a result. Couldn't tell you way exactly, just a personal preference. And I use male and female characters almost equally, since I care much more about class. If I have the option, I go with my whim. If I'm playing something for the second time, I'll usually try the sex I didn't use the first time.
Favorite class ever: Samurai from Final Fantasy Tactics. Blade Grasp is so strong it feels unfair. Draw Out consists of decent-to-awesome offensive and defensive skills that require no charge time or MP usage and are immune to Brave or Faith effects. That way you can create a low-Faith character with offense, defense, and support skills that can use MP for MP Switch. Giving Draw Out to a Wizard, Priest, Oracle, or Summoner is the ****ing greatest.
Least-favorite class ever: Battle Suits from Disgaea 4. I love most of the Disgaea 4 classes and characters, but Battle Suits are just lame. They're decent fighters, but automatically self-destruct when their HP goes below 10%. I've had one at full health gain 40 levels after one attack, have its HP below 10% as a result of its new max HP, and then die. **** Battle Suits.
