Getting bashed is something that will happen a lot. Generally the group has a tank that absorbs the damage and bashes while the rest of the group does the dirty work. You are allowed to play two characters from the same IP and email this wipe, I would suggest trying to use one of them as a tank and the other as cures or damage.
As far as negating bash, there are a select few items in the game that make you harder to bash and sometimes immune. These are hard fought over and hard to obtain for a newer player. New to the wipe is a bash_mod rank that would help you avoid being bashed. It is long rumored that the dexterity stat will help bashing others and also avoiding being bashed.
Good luck, have fun.
