I want to discuss stamina sustains vs. other sustains. It would seem stamina sustains are meant to be one at a time, max 2 at a time if you're using the cheap ones, maybe 3 at a time at lvl 50.
Shadow Combat - 20
Shadow Feed - 40
Exploit Weakness - 30
Berserker - 40
Blood Frenzy - 100 (!) and drains 4 per turn
Aim - 20
Rapid Shot - 20
True Grit - 70 (!)
Precise Strikes - 30
Precision - 50 (!)
Momentum - 50 , and drains 6 stamina per turn
Slow Motion - 80 (!)
Expert Strikes - 50
Arcane Combat - 20
Arcane Feed - 40
Superiority - 80 (!), and drains 15 (!!!) per round
Shattering Impact - 40, and drains 15 (!!) per round
Total Thuggery - 40, and drains 12 - Skill level per round
Breath Control - "only" 15, but costs you global speed
Shield Wall - 30
Last Stand - 90 (!)
Right considering that most stamina based classes doesn't gain any benefit from Willpower other than Max Stamina and some saves, the average lvl 50 stamina user (Zerkers, Fighters, Brawlers, Rogues, Shadowblades, Marauders, Archers more...?) will have +- 400 stamina these can be very much for non-lvl 50 characters to have.
Most stamina actives are also fairly stamina heavy, leaving stamina users often depleted of stamina, much more so than mana or other resource users. (IMO) Some people may call this balance, or trade-off, but for me, it detracts the enjoyability. I hate having rushed in, used my shield, then whirlwind, then flurry, then... oh, my stamina is up. :-/
Rather give me something to do, than to strand me with no stamina. (Ie. Longer cooldowns is better than high costs/low stamina pool) There is no strategy in using teleport (or stairscumming) and resting for stamina.
Archers have a good system with 1 cheap low stamina/low cooldown option, which can be used ad nauseum. But most of the melee classes doesn't have a "steady shot" equivalent. Which I think is a shortcoming. Mages and the like have several cheap options available to "keep them going", bread and butter if you like, which the stamina melee guys mostly lack.
Rush is an enormous stamina cost especially with a fair fatigue level, it can be over 40 stamina, 10% of a lvl 50 char, much more on a lvl 10 or 20 char. Anyway, IMO stamina needs to regen quicker, and/or sustains cheaper and/or actives cheaper. But lets discuss.
