{P.V.P} - Player Versus Player should be available in the game.
{New Weapons} - New weapons are needed for the game such as Daggers with very high attack speed (but obviously still stronger than Guns) or Spears
with good reach.
{Equipments Bounding} - Players should be allowed to remove they're Shields and equip the same weapon type as the first one they have equipped so
that they can have DUAL type Equipments. Like wielding TWO Swords, Daggers, Guns or Spears.
{Monster Hunting Quests (M.H.Q)} - M.H.Q's should be made in the game that gives Crowns and Energies or new Equipments and Items as rewards for
completions. Just to make the game more FUN and INTERESTING. with this way, MORE people will come and play
this game.
PVP - Eventually. The game had PVP before the public launch IIRC. The Devs are basically "fixing it" right now.
New Weapon Types - I don't know about daggers and spears, but new weapon types are always welcome.
Dual Wielding - lolno. Shields are too essential in this game, specially if you are going solo. If we had some kind of "dodge button", then maybe dual weapons would be ok. Other than that, no. (and no, defending with a weapon is wrong too. Shields have stats, health, resistances and such. You shouldn't put that in weapons).
Generic MMO quests - Boring, just like 90% of every generic MMO with generic quests. I prefer new stages/levels/Stratum/Boss/Tier. This is fun and interesting.
Also, just saying, but I don't think that "OH LOOK WE HAVE FETCH QUESTS" is a good way to promote a game and attract more people to play it.
