I hated merit grinding in XI; it was soooo long, sooo tedious D:

I wouldn't be opposed to seeing something like Borderlands 2 Badass Rank system though e_e... Complete a challenge, get a point to spend wherever, increase potency of skills by like 0.4% so you have to complete lots of little varied challenges to get anywhere instead of sitting around hitting your haste macro for 5 hours lol
