I'm for a blend of both systems... And then a XIV spin on those systems as well. I'm all for a chain system, and I think that it is a must. I like the visual feedback from XII, where you could see your chain level, and as it went up the benefits got better. But I'm not for killing the same mob over and over again.

I would take a blending of both, where one one hand, it's about killing mobs and chaining kills together, and having that feedback shown on the UI.

The thing I would change (from XI) is that there would be a much higher level cap and that each level has it's own time-out before it would "level-down" to the previous level or reset to level 1.

I would also add that you would fill up a xp bar for the level you were on (say level 2, and it would need 2000xp to go to level 3) you could kill some harder mobs, or string in some lower level mobs together to fill up that bar. (This all would need to be adjusted and tested, the numbers are just made up examples.)

Anyway, while my explanation isn't very detailed, I'm all for any kind of system that promotes more party play, there are positives and negatives that's for sure, but I think the positive outweigh the negative.

Hopefully we'll hear some info on this, or at least know that it's been reviewed and sent to the dev team for response.
