What will be of the "Less" classes?

Well technically, you could just pump points into hp.
But then that lowers your almighty damage.
Your comment just looks like you don't want your damage to get reduced.

the damage is not important 0_o. look how i started the thread, the accuracy is the main problem so far since the char wont be able to hit anything just because the stats are in only 1 group what destroy almost all the "less" chars

lets say you are in advanced lvl like 160+ , you will have to train at least more 10 ~15 lvls in way way lower monster to gain AP stats to put in the secondary stats to give a small chance to make you be able to train in high lvl mobs again? is that fair?
