Blessings, Bonuses, and Enchantments
I'm a big fan of rpg games, been playing them since the NES system. I was always the type of player who liked to max everything, collect every item and overwhelm whatever the next phase of the story had me face.While not everyone played this way, a good portion of the fan base did. I realize that this is not a straight up rpg, but ffxiv uses many elements from them.
Having said all that, I'd love to see some additional ways to be gain an advantage outside of just gear. Perhaps allow players a weekly quest that let them choose a small bonus to a chosen stat, similar to materia until the weekly reset. They could even be tied into the existing weekly challenge log. Speaking of which, I think it would be awesome if certain long term achievements gave out really small permanent bonuses, like a +1 to determination, or +50 hp. Nothing game breaking, but cool incentives for players like me who like having every small advantage possible.
It would have also have been fun if before any dungeon or trial for progressing the story there was the option to hunt down items to assist in the battles ahead. Maybe a Water based enchantment that gave addition damage or reduced damage during the ifrit fight. Once again, nothing that would ever be a requirement to do the content, but there for anyone interested.
