as i just started to play im not sure what is reported alrdy and what might be PC spec dependent.

BUGS:
+ toggling the minimap does not work in most of the cases. i press the button (default 'TAB') but nothing happens.
sometimes (10% of my 12 hours) it does what it is supposed to, like in standard d2 lod.
+ sometimes items of my inventory do not show the tooltip. i need to manually click for them to see the tooltip info board after around one second.
+ dialogs in video sequences do not show the character name but instead say 'Player: ...'

GAMEPLAY:
+ it would be beneficial to indicate every single buff that got triggered by the passive tree/skills/shrines. to me it looks like, that at some point there is an indicator for certain buffs but not in any case
+ add the real numbers to some kind of 'advanced tooltip' to the skills to get more in depth-information. right now one needs to compare the stats in the character screen and take a look at the details of the numbers that are shown on the right side of the skills. but they are not visible in the tooltip as far as i can see.
+ add level requirements to potions, gems, skills and amulets (if not, playing a second char might become trivial and feels like a waste of time)
+ add a quality of life feature for the shop, that somehow lets you mark items and sell them all by one click as in the win explorer interface by pressing CTRL+SHIFT
+ for now i just take a mage off-hand and a unique mace that makes me immune to any crowd control, to have a rage spending sink hole. this way i can get willpower fast and heal myself with the melee weapon bleed thingy. alternatively i could take a pistol and throw bombs to spend rage.
i think thats not very 'trve' mage-esque as i expected. will there be a solution to finally spam stuff as i was able to do on my nova sorc ^^?

i might find something else of interest in the back of my mind, but for now thats what i can report.
