I don't support this idea at all.
I personnally hate that achievments point system..
It's only farm for farm for farm for farm for farm. xD Like you keep farming and it can be soooooo .. "time-eating". I know there isn't much to do IG, but what did you expect from Pokemon ? > <'
I experienced that in WoW for many years (I played it 4 years so x.x) and honestly I was so frustrated to not be able to accomplish certain achievments because I was more a solo player etc... And some were reputation farming and so one, it just began to be more and more pointless and started to depress me to be honest. xD
Achievments are everywhere now, it's so tiring.
Plus, achievments points would be another way to judge a player like : "Ehhh he's a noob he doesn't have many achievments points/that achievment !" Or, the contrary "WOAAAH he got so many achievments points, that guy is strong !" (No, that guy just doesn't have a life and keep farming everyday on the game XD)
I think the farm system in the game, even if it's very reduced to breeding and the Islands is still a good thing, 'cause you know that after you finished your breed, it's gonna be over, done, finito !xD In real MMO you're like : "OOOKAYYY ! I'm done with this ... Oh f*ck me, there's more ?! pfffff... *loose days and days of life*" (<--- and that's a true story XD)
Even if I can stay out of this system and not using it, I don't know, I'm not for it.
Sowwy. :( But it was a very good idea though huh ! But I don't think it would suit PokeMMO to be honest. :/
