You can already raise Enmity+ to 5, I thought? Point taken though. You're considering raising:
1) The number we can store.
2) The number we can distribute within a category.
3) The number we can assign to any one stat.
Please do the first one ASAP if you're going to do the latter two. I've been sitting with capped merits since a week after the last time you expanded the system.
