i agree that you might feel a bit slow by your stamina consumption/preservation and absolute mad low base health

but considering how poor the boss fight mechanics are, its more or less justified
but if the game gets more mechanical boss fights in the future then id probably start asking for more realistic stamina consumption with more abilities such as shield bashing/interrupts and etc

but as the game is played right now, clunky stamina and health is to be expect for balancing reasons
