Yes and no. It forces warriors to think about what they're going to do (can't spam power attacks or shield bashes), but the problem with it is that it forces you to rely pretty heavily on alcohol and potions early on. One is almost constantly opening one's inventory to drink potions or alcohol just to keep up.
However, I do hear that it evens out at higher levels, I'm just not sure if I like that lower level folks have to rely so heavily on consumables.
Though I understand you point about lower levels relying on potions, but isn't that kind of the point with being low level? I mean, you're kind of weak at this point so you should have to rely some on potions and or tactics. And it should get easier, stamina-wise, as your character becomes more powerful (not that the challenge overall should get too easy).
I haven't looked at the perks all that closely, but are there any that reduce stamina drain?
