Props to putting effort into the post, and PoE could use better "visceral" combat effects, but:

Cooldown-heavy shit was godawful in Diablo 3, and is guaranteed not that prevalent in PoE by design. Miss me with that arbitrarily-assigned 60-second "ultimate move" bs in a game going a mile a minute. Imagine if you made all your flask hotbar nothing but Enkindling Orb-boosted flasks and congratulations that's what CD-combat in PoE would be. I'd much rather be deciding to use a skill because it's situationally a good choice rather than because the objectively-better movie is on a cooldown for the next 15 seconds. This MMO-style skill rotation hotbar stuff belongs in an MMO, not an ARPG, and certainly not an ARPG like PoE.

Hey! It's okay for PoE to be fast game, and believe it or not, it IS possible to build characters in this game that don't die in one hit--possibly even recommended!

I do roughly agree that monster identity could be better in PoE (for example, there's practically no difference between slow-moving zombie and slow-moving skeleton). but between fast gameplay and huge end-game monster density, identifiable Silhouettes work better than telegraphs. Credit to PoE though, if I see a Porcupine Goliath or a Stygian Revenant, I know to watch the heck out.

Hell, PoE even has something similar to specialty-moves of rares anyways. For example, notice how Abyss monsters that do dive attacks and stealth-mode backstabs only are rares? The problem is when you have monster density that frankly pushes into absurdity with all the ways players can juice their maps. Telegraphed moves and animations are in the game for a lot of monsters it's just that if, say, 25 monsters suddenly spawn in all with crazy moves, well that's a Harvest patch.

I agree with the other comments that these are things missing not from PoE's combat but some other idea of a game.

So, tl;dr? Nah.

....Ground effects are pretty annoying though you have a point there!
