1. tria, hexa, octa ect. should be introduced in the next release cystal blue (CB), which is said to come out in a few months ...this year supposedly
2. don\'t worry about the advantages/disadvantages (including rich/poor) at the moment, because the skill system isn\'t fully integrated yet ...again CB along with trading and fighting ...but i think the idea is that you have the advantage/disadvatage number on 0 at the end ...no idea what happens if not ...since it\'s not fully implemented yet
3. it\'s a skill-based system, so i don\'t know how heavily the stats will get affected ...i mean, you already diced and sorted the stats, before the adv./disadv. menu comes.
and, yes, as far as i know, they\'ll remove the whole character database ...but i think they said we\'ll be able to \"register\"/secure our character names, so they\'ll reserve them for you.
