I quite like Eureka, it's mechanics are a nod to FFXI - pretty much any death/KO there loses XP and yes, you could de-level, which made end-game fights intense as wipe too many times and you end up too low level to actually partake in them. Plus you could only change jobs in your Moghouse (instanced house within a city/town) so if you were half-way around the world and needed to change jobs - back you went (and there was NO flying mounts, no quick teleporting - you had to hike back yourself - I believe they've added a few things in since the good old days so I don't believe it's like that now). Still, there's a good mentality around it where folks help each other out regardless when they can, they wait for others to arrive before engaging a world-boss/NM, plenty of shout-outs and chat going on. It's not for everyone but for someone who's first MMO was FFXI, it's a nice bit of nostalgic gameplay without re-subbing to 11.
