As a loyal ffxi player, i started playing FFXIV and noticed these 3 things that would determine if i personally would continue to play this game or not:
#1: Auction House - badly needed in any online community game
#2: More Storage!!!!!! As the game has been promoted with all of these great ideas about the lvling system, crafting system, ect. to be for players to be able to make their characters more personal, i have found myself stuck in a spot to lvl or craft at all due to no space to put anything. In order to lvl i need better gear, with crafting you cant make any 1 item without learning another craft with it, and in order to make that other item you need to learn another, and another, so on so on. so here i am with crap armor, no space to put any of these crafting items that i Need to lvl my crafts with, and just stuck.. In ffxi we had a mog house, that was a great idea, had space to put stuff, and quests to do to get even more space, worked perfect. So please impliment something to that effect and it would make teh game alot more appealing to other players.
#3: Recipe List! - As far as crafting, most are half tabbed out looking online on another website just to have crafting recipies to look at in order to craft, without these websites it would just be like most of this game so far.. pure guessing
I have seen alot of players start this game and love the start of it, and then they get to where im at, Stuck. Then they just quit playing and tell everyone else "dont bother with ffxiv, its just a crafting game that needs too much work to be any fun". I hate to say this, but i half agree with them. As for me, untill some of these necessities are implimented i dont think i'll continue much longer either, being stuck as i am. But as soon as they are i will be back and ready to pay to play :)
