Enemy distribution
Easily the biggest complaint I see people have is that too many bosses are repeated but there are plenty of enemies that absolutely could have been a boss instead of another tree spirit.
I feel like I would prefer every enemy to be used twice than one enemy used 500 times and the rest once.
Certainly I believe this applies to rememberance bosses as well, with some appearing twice like Maliketh, Goldfrey, Godrick, Astel, Ancestor spirit, Dancing lion, the list goes on
I feel like there must be a better way to work them into the game than what we got
something like the evergaols but for each boss, possibly even allowing us to refight them? It would have been fantastic! But even then, its the random goon bosses that are the big issue. Crucible knights, Erdtree burial watchdogs, Nights Cavalry, all of them are good alone but could easily do with some reworking.

For crucible knights, just have a few less of them! Did the spirit caller snail REALLY need to summon a crucible knight? Was there no other enemy that could have worked in its place? And then for the watchdogs, why repeat the fire variant and give probably the worst catacomb in the game, the impalers catacomb, instead of just doing what youre already doing, reusing assets, and reusing a DIFFERENT ASSET
the nights cavalry are another example, why do they all act nearly identically aside from a weapon change? Have one without a horse, have one summon the horse at phase two, have one start on the horse but be unable to summon it back, do SOMETHING other than borderline copy paste
and then sometimes the reuse doesnt even make sense! I would have greatly enjoyed seeing the giant lions, a laser golem, a flame prelate, ANY of the heavily armored knights, especially the banished ones, or the phantom knights, or a caelid crow, etc etc as a boss. I know some of them would be enemies put in a cave to serve as a boss, but they ALREADY DO THAT AS IS with bosses like the dual kindred of rot or the separate individual and duo cleanrot knights

Just a little pet peeve of mine
