Onto stamina+ auto attack compatibility
I can see stamina and auto attack existing together if they go the following route. stamina costs are striped completely from every action that has the limiter of tp mp or a timer. The 1 slot is changed from the basic attack to a auto attack toggle. Attack Speeds are assigned to each weapon this background damage and tp generation is free of stamina cost as well as continuing to proc while being qued up for a battle regimen. basically your character is always doing something.
Stamina would still be burned by the execution of secondary attacks or actions such as throw, guard, heavy slash/stab, broad heavy and full swing ect. These would be at will actions with a hard limiter on there use from stamina costs. Tp balances its self out a bit with the current system of accruing it. basic attack damage + math magic = amount of tp gained. now when you are fighting a higher ranked mob the amount of tp you gain takes a dramatic swan dive because you are not throwing out as much damage from your basic attacks.
Now let me throw that all into a blender and extract an example of what I'm blathering on about.
Lets say you and a group of friends are out beboping around. All of a sudden the rare and notorious nasty one eyed albino spriggan appears. Jumping at this opportunity for fame and riches your group engages. Every one engages there auto attack and start to nickle and dime the mobs hp while gaining a bit of tp at regular intervals. Wanting to get this bugger down as quickly as possible melee's begin to use there secondary attacks burning stamina for extra damage and to gain tp at a faster rate. Even the mages can get in on the raw dps action by activating auto attack using the sub target reticle that people seem confused about for healing/buffing while staying focused on the spriggan of doom and tossing out the odd radiance/damnation or levinbolt/flashfreeze and using the fireworks we generally haul them along for.
Now the wrenches in the works comes from archer and the boogeyman of the targeting systems current oddness when it comes to subtargets. The mechanics of multi shot would have to be changed, I am also a bit hesitant to force archer and future ranged classes into a full-auto mode due to the inherent costs of munition use.
