I saw some arguments that the stamina bar adds an extra level of strategy to the game. While I used to think the same way I feel that is laughable now. Seeing as the same effects can be achieved by using the restrictions already placed in game.

Regardless,
Responses seem to be about 50/50. I think a compromise is in order:

Limit the stamina bar to effect certain abilities only.
- power-up type abilities: taunts, second wind, speed surge, ferocity, spiritbind, etc. (even some of these I am reluctant on)

This leaves out:
- spells, weapons skills, normal attacks, bought attacks.

So how do we make a difference between big/small weapons and big/small attacks with no stamina bar!? ohnoes!
- weapon delay is a clever idea: doesn't have to be like ffxi and could be universal for that type of weapon, is tied straight to the swinging animation. As for attacks; my bought attacks, seeing as they are much more powerful... *cough* would simply have a longer animation time on them, in the exact same way as some weapon skills take longer to pull off than others.
- If they add auto-attack, something similar to weapon delay would probably be implemented anyways. If they didn't add auto-attack you would just spam your attack every time the universal cooldown was up. Which honestly isn't much different than what we do now. Also no different than what rangers had to do in ffxi to spam range attacks, there was no auto-arrow. Although a visual this time would help.

How do we make a difference between Blizzaga 19 and Fire 1 with no stamina bar!? o_0
- Obviously simple: longer/shorter casting times, longer/shorter animation times (spell ending lag), cost more/less mp.

@Aldarin
I see what you mean about casting time and animation time being the same thing. I still see them as separate though because I can increase/decrease a spells casting time in addition to its animation time. Example: Chainspell from ffxi allowed the mage to cast with no cast or recast timers, but the animation of the spell leaving the mages hands was still a limiting factor. They could only fire off spells as fast as the animation would allow.
