actually it occured some time ago. the sp system basically made it so you dont fight things that are difficult, and thus most people never fight the monsters with different battle mechanics.
This is why people complain about powerful attacks that can one shot most people, because you were supposed to avoid or stop them from happening.
an excellent example is the puks, low level critters, but their flip kick is completely avoidable, and stunnable. higher level versions get access to tail chase as well, which makes you watch for which WS they are using. they also have enough dmg for thier level, that is almost always worth it to try to avoid these weaponskills.
high level cocatrices, have a variety of enfeebles that a healer would love to remove.
sheep have aoe sleep bubble, the longer you sleep the more dmg it can do, but a ranged player can pop it early allowing melee and tanks to continue
impish incantations? man i would love for someone to stun that at any level
undead have strong dots that healers will have to deal with
Piestes have gaze paralyze, if the melee arent paying attention to his eyes they can get frozen, the tank has no choice, so if the mages dont get paralyze off fast people will die.
the problem isnt that they dont have complex mob and battle mechanics, the problem is that there is no longer much reward or reason to fight all the different mob types, and when you do its usually fighting versions of them that arent high level enough that you dont just steam roll them before they do anything.
far as stamina, what i dont get is people complained that they had to do to much in battle, and so they want auto attack. Then people complain that stamina is not allowing them to do more in battle. If regular attacks were weak/didnt have different functionality i could understand, but they are pretty powerful, and when im on pug, im actively choosing to use either flurry, pummel, light strike, or heavy strike, they all have different uses and advantages.
Anyhow managing stamina is a big deal, I think giving you the option of spamming many abilities fast, or holding out and slowly using whats needed, but maintaining the same overall amount of attacks was a great idea.
But its going to change, honestly i really dont think most of the changes you guys want are good changes for gameplay, they sound good when you say them, but once you start to really think about how it will actually work it usually doesnt achieve what you want to achieve
