I'm seeing a lot of "if you have Haste"; "Haste is the key" type posts. Surely if success or failure is dependant upon one Spell, then the balance is wrong. If you are forced down a specific route in order to "win", then you're no longer role playing.

Personally, I've had no real difficulty with combat on balanced until Act 3. Once in Baldur's Gate, almost every serious encounter ends with me having my A**e handed to me. The only exception to this was
Auntie Ethel, She was easier to take down this time than the first
. My party are all Level 11, but all seem to be seriously weak against multiple enemies than seem to have 3 or 4 actions to my 2 (not using Haste).
