I have been recording notes on my experience with the game. I’ve only been playing for the free session, so I am not far in. I’m interested in playing more after the free weekend is over, but this depends heavily on the kind of reception this post receives.
• Tells
In general, combat feels fine, but without clear enemy telegraphs it’s difficult to master to the point of frustration. The variety of enemies is a double-edged sword in this regard, with different foes attacking at different speeds all at once. Sometimes, they’ll give an audio cue (like a grunt or windup sound). It doesn’t really help at all for pattern recognition because for some the attack comes immediately and for others it’s a .3-1.3 seconds of wait. I do appreciate that it’s usually pretty clear when an enemy is going to perform a rush or ranged attack. However, for most other attacks it’s difficult or even impossible to determine what they’re going to do. To add to this dilemma, adding specific audio cues - while helpful - presents a problem for impaired players. If that’s not a consideration, please disregard. If it is, enemies absolutely need better tells.
•Patterns
As far as I’m aware, it doesn’t seem like enemies have a pattern. This is not normally an issue (I’ve thoroughly enjoyed games where the attack chosen is from a pool). Given that every enemy has a wildly different timing on their attacks, it’s not plausible to expect players to somehow inherit a pattern of enemy attacks from the ether when they’re surrounded by 3 mobs that attack differently and out of sync with one another.
•Camera
The previous two issues are compounded by the fixed camera. I hesitate to call it fixed because for some reason it seems to gyrate subtly, which I am certain will cause vertigo. I have no personal leaning for or against a fixed camera, but much like the games of the late 90s and early 00s, it often works against the player. It is even weaponized against the player like in the Iluna Caverns (I am sure I got the name wrong). There are times you will get attacked by an enemy who rushes from offscreen and unless you’re psychic you’re not gonna know you’re about to get hit by an OTK combo. And sometimes you get get slammed by a boss whose attacks fill the entire screen, despite that you cannot see or hear them. The overhead camera makes determining enemy tells (if any exist) more difficult due to how “noisy” the screen is and the perspective. I’m not suggesting the camera position needs to change, only that it’s position needs to be considered when creating enemy tells.
•Difficulty
I will reiterate what has been said before, but the difficulty of some content (bounties and i think crucible) is hidden from the player, which will absolutely deter new players. They may be led to believe that the content is ready for them to complete immediately because it is offered immediately upon unlocking the feature. I’m all for keeping this content freely available to characters of any level! But unless there’s a challenge rating associated with the content, new players might just as easily assume that the entire game will be that hard and quit. I threw myself at them because I’m stubborn and want to learn everything the hard way. 
•Gear
Two handed melee weapons just feel straight up superior to everything else. I’d argue it would be useful to give one to new players as a freebie (I don’t know if that’s a thing or not; I found one early enough). I won’t make any comments about balance due to my limited experience with the game.
•Friendly fire
Y tho
As a footnote, I really enjoy the game and look forward to playing more.
