Yes, because CP doesn't chain. My XP:CP ratio was easily breaking 10:1 when I was messing around with it this morning.
200k XP Solo/Trust in Adoulin shouldn't take most people who farm AAs and thus actually need the merits more than an hour and a half.Edit: I may have misunderstood. But still, you'd get several times that many cp if you're talking about the time to get 20 merits in abyssea (30 minutes or so).
EDIT: OH SHIT typo + not paying attention :*(
I meant 15,000 CP, not 1500. The point still stands, though: KIs are not a long term here.
