I'm curious to know if advanced classes (or skills) are planned for the future? I think they could be really cool, for instance:

Dark Knight
Requirements: Necro 75, Psychology 75, Endurance 75, Sword 75
-Life steal abilities
-Mitigation abilties
-Summon undead abilities

Chimera
Requirements: Cow 75, Deer 75, Spider 75, Bat 75, Pig 75
-Ability to shapeshift in combat to new forms
-Hated by druids and animal town
-Can freely shapechange from animal forms
-Special Beast form

Skald
Requirements: Hammer 75, Bardin' 75, Mentalism 75, Shield 75
-Sings, thereby doesn't require an instrument
-Vocal attacks
-Lighting attacks with hammer/shield

Flower Child
Requirements: Druid 75, Gardening 75, Flower Arrangement 50, Mycology 75, Nature Appreciation 75(50)
-Natural Animals will not attack (unless provoked)
-Can cast buffs similar to flower buffs
-Can summon fae guardian

With the vast amount of skills in PG there are probably thousands of possibilities. As a player, I always like trying to achieve the next thing--there is a ton to do in PG, but I wouldn't object to a ton more
