Part of this issue is Yoshi and Co are copying everything and pretty much anything from other games and do it very badly. Now Yoshi could take some systems from XI not just mobs, there are plenty of endgame systems that could be borrowed and improved on. For example the loot lockouts could be changed to a point system where your contribution is what nets you the points, instead of a week lock out, players could access said content every 2 or 3 days. Things like this would go a long way into improving this game.
