Warriors after big bang / chaos?

I've quit for a really long time. Can someone tell me how to add stats to a warrior after big bang and stuff? Is it still 4 dex is the best? I have little funding - a 11 atk wg, 20 dex robe, and about 20m. Thanks.

Sorry if wrong section, I just need a quick reply.

Also, if there any skill builds. Any warrior guides after big bang would be much appreciated.
