In my opinion its a bit unfair, if is a stack sub we already dont have stack in armor... at least we should have all skills stack including transfer(its a new option from garcia/epilogue), i think it nop became a OP classe. And with the change of the buffer, loosing the special buffs... (that in my opinion should be all buffs like 1 or 2 hours) half of the players of server ill be boxes because no1 ill want to be se or ee because dont have the transfer skills in a non healer class, rising the lag in server.
And for some reason if a healer switch to another class(learning frogotten scrolls for exemple) it ill lose all the skills forever... at least was what happen to my ee+fighter i lost the pomander and the skill...
