When played on client it preforms much better than it does on facebook

I would say the major gameplay points on delteria right now would include:

-Many collectable weapons (Melees, swords, staffs) Including a player economy.
-Quests and a leveling system
-A perk system to let you decide what abilities you will have in combat
-A major focus on dungeons and party raids. It is shifting more towards teamwork in upcoming updates.
-Typical Job systems (Mining, fishing, farming, panning, ect)
