I agree that more dialogues for event would keep players interested in the game. After all, it fleshes out the game's character and makes them feel "alive". Referencing from Age of Ishtaria game, some of their events have a decent length of story and the characters are well fleshed out compared to VF. PVP is another factor as well, its practically suicidal for new players. I remember just starting out with in arena and already meeting people with 5*s compared to my only 4* leon. So yeah unless they have the patience or money to spend and build to tackle arena again, arena won't be an attractive feature for them.
But then again VF is still considerably a new game, Ill give it a few more months before deciding.
