I think they should bring back the toughness that was XI, Not saying bring back death penalty but at the same time look how effective it was at toning the skill sets of players and not get that mentality of " oh what ever we can just wipe and do it again over and over " XI made it so you really had to make strats really had to focus on your role.
With that said though I think the leveling of XI nailed it on the head as well you really fell in love with that job you got to 75 you had a connection and wanted to perfect it. A: not only did it take forever yea got it. But there was no ( maxed out every job and craft ) so in turn i think they need to take a step back and really make the future of 50+ or 2.2+ and Not make it as hard as FFXI but not so face rolling as XIV is now. I miss the fear! I miss the CHASE of a NM spawn the heart pounding seconds b4 you seen if the 48 hours of waiting was for a super rare item or for a wind crystal. ( which could turn and fix the horrid economy )
