Ideas that the game could have...
1. Open world PvP with a status on PvP players.
2. More dyes more house and weapon dying and housing items being able to dye metallic colors.
3. Glam gear with no restrictions asides weapons to any class.
4. Beastiary. It'd be interesting to have 3d model to look at and lore to read maybe art for locations and display for all gear.
5. More creative spears and books. Samarai Swords for DRK.
6. Transformation Class. It's neat that in story Thordan and Iceheart transform into Primals themselves to fight and use their abilties also.
7. Make Ehcnida card unique to only being able to obtain once.
8.Lore and Fenrir Pup only for winning not losing in Feast. Losing is the quickest way to either and when you got a healer only caring for lore currency this becomes a problem in the Feast competition.
I've a lot more ideas but this is all I can post in a 1000 letters.
