I have Stamina builds that are only lvl 32, 30 and 28 and I run out of stamina when fighting the harder mobs for quests and have to just stand there and hope I can kill it before it kills me with just weapon swings.
We don't have the CP to reduce the costs like higher level characters and it seems that the attacks take to much stamina. This is the most noticed on the two handed weapons.
I have to stand around waiting for my stamina to regen before I can attack anything else. This is kind of boring!
I am using food or I'd die all the time.
