re: proficiencies.

yes, you get back all your berserker profs when your new class exceeds the old BUT if they were weapons that the new class cant use then youre sol.

now assuming you planned ahead and put your berserker points into warhammer, flail and/or dual wield, you can put the new class points into some other weapons such as mace, club, and sling (the points from the two classes do NOT combine, so if you have 4 in hammer when you switch over and then put 1 in as a cleric, youll still just have 4 when you get the 1st class abilities back).
