Height advantage - dont mind that.
Backstab should only be applicable when the target is flanked.
Disengage / Weapon Swapping should cost an action.
Shove Should cost an action.
Fighters should not be turned into FF14 characters with big flashy abilities if that happens I am going to complain so hard about a refund its not DoS it was not advertised as DoS it was advertised as DND 5E as a game.
Mages do need divine spells removed.
Also less explosives and larger than average hp totals for enemies when your fixing that.

Except the fighters thing the other stuff could all wait to be patched till later in content.

The character creator needs a massive overhaul honestly.
Rolling ability scores option.
Equipment selection options.
More general character options. Height Weight Size ect. Voices.
Multi-classing in character development.
Mercs.

Again this is something can wait for all the classes and races honestly to be corrected.

The comment were not really adding new content in patch 5 really is not an impressive thing to say like I said a while ago 2023 release at this rate. They already made the comment 2022 is a hope currently they are unsure they will make that release date. With news in this patch I would not be shocked even if it got pushed back to 2024 lol. Not to be a negative nelly but its kind of true. Glad I invested in pathfinder wotr with the rate content is coming out for this. Its one of those situations where I would not be shocked if delays are because they were pushing stock up to sell off the company or to drive sales on another divinity game with bg3 really not being there main focus. Just more a publicity stunt.

Fixing long and short rests is an easy fix. Add random encounters based on map location when returning to camp on a random variable. This would encourage more use of short rests and it would honestly add more flexability with the game and less save to avoid results as well as by adding random encounters with some random loot options people want the loot but also they dont want to get caught without having rested. They could even do it as a level tied encounter possibility. Random mini map locations for the encounters could also help resolve height advantage in as many situations as its present currently for people frustrated with this by making more situations where height may not be reliable.

If they were really serious on resolving things classes should be the primary focus on releasing content. Once all the classes exist then at least your resolving all issues at once and giving everyone there options to play what they want to play rather than hey were just fixing a bunch of bugs and mechanical issues as a patch. Fixing issues is important when the game is broken and you physically cannot play the game. Massive Lag, Content crashing, in ability to save serious issues with emergency fix needs not minor bugs like a cinamatic needs to be corrected. A mild pathing issues. Those kind of things that need to be fixed but are not major can be fixed in between patchs.

Its baffling how they have so many people on staff for a single game when you have much larger games with much smaller staff having much smaller issues with content. MMo's I am talking about in this regard as they are massive multiplayer games and the staff for most of those games is around 200 on staff members for the content. Larion has 300 people on staff and they are having trouble managing to add even classes to the game on a regular basis. There are plenty of ways to be more efficient at what they are doing than how they are doing it.

4-5 People sifting code for ways to fix specific issues while the rest of the staff is focused on more extensive content can generally resolve most issues. Honestly it comes off extremely disorganized and like they do not know how to handle content release. They are just really bad at how they are approaching the game while I would not want to see it pushed like cyber punk 2077 the difficulties they have for the amount of content they are releasing is mind boggling.
