This isn't really a suggestion thread, so you can move it to the Riverside Inn if you want...
I was combing through the bestiary and found it interesting that one of the Factions classes - the Ritualist - was the actual name of a White Mantle creature from Prophecies.
That got me thinking - what if the development team decides to get "inspiration" for Chapter 4 and beyond classes through looking at prior creatures? I came up with the following possibilities:
Avenger (from the Maguuma Avenger) - a class specializing in snares and punishing enemies for attacking their allies
Scout (from the Centaur/Stone Summit/Dredge Scout) - a class specializing in evading trouble and removing/disarming/countering snares and time-released damage spells
Chaot (from the Charr Chaot) - a class specializing in disruption and chaos magic
Brute (from the Dredge Brute) - a heavy melee warrior-like class focusing on overpowering attacks and little armor
Seer/Sage (from the Dredge Seer/Forgotten Sage) - a magic using class that specializes in attack-enhancing enchantments and divinations
Beastmaster (from the Summit Beastmaster) - a larger expansion of the ranger's beastmastery attribute, with control over larger animals and forsaking personal attacks
Arcanist (from the Forgotten Arcanist) - a magic using class specializing in ancient rituals that call forth "wrath of god" type damage
That's all for now...I'll keep searching...
Please feel free to add any other existing creatures that you can see as a stepping stone for a potential new class.
