I had some class ideas as well ^^
-Elves: Winged ranged attackers. Can conjure many buff and heal themselves and others for a lot of health, but as a downside have low defense and are often attacked first.
-Venomancer (Beastfolk): Humans, mostly female, with the features of animals. Know many poisonous attacks, mostly long range, but have decent short range attacks. High attack, low defense.
Can tame animals with a lower level than themselves.
-Assassin (Merfolk): Very high attack, speed and agility, but lacks in defense massively.
Sneaky attacks, high stealth, medium regeneration.
Can activate merform in water to increase attack and speed even further.
Thief (Human): A lot like the Assassin, but more balanced out in defense and health regeneration.
Can carry along one pet, unlike the venomancer, to grant them some buffs and help in attacks.
(Would be received as a basic quest or something.)
Dark elves: Opposite from the elves, often portrayed with dark skin and light hair (also opposite from normal elves). They can heal themselves, but not others, and only cast debuffs on enemies. Higher attack and defense than the elves, but mostly seen as a solo class.
Mystics (Human-ish): Mystics are perfectly in tune with nature around them. They harness the power of pure energy to strengthen their blades and fire terrible attacks at enemies. Can also summon plants to do their bidding and temporarily receive the aid of wild animals.
Hmm, have this so far. Will try to think of more later.
