I belive Grayface's mod improves (I'm not saying "fixes" because you can't know if the nerfing wasn't intentional) dual wielding, so you might want to try it.

Quote from readme:
FixDualWeaponsRecovery option fixes wrong recovery time calculation for characters wielding a weapon in second hand. Dual-wielding was useless before the fix due to doubled recovery time. After the fix it works as in MM7 and MM8.
