If you compare stats in early access races will feel unbalanced to an extent cause your capped at level 4. Weighting out later play it checks in line more so.

Fire resistance is very strong through later play when you factor spells like fireball ect. Early access thats less of a factor also more tiefling subraces will eventually provide more options and the class choices are more valued in EA. Hopefully we will see racial feats and more half feats as well which will counter balance this.

Shield Dwarves and Githyanki are over powered in early access where there racial benefits make the non melee classes feel much more powerful. Later play that tones down so its less of a factor. Though having stat rolls would also make this feel less important later. Loosing movement is a big set back for dwarves and other small races.

Humans are less wow overall unless you can roll stats that +6 stats overall is kinda meh I do think they should add varient human but its less powerful without the feat choices however it is the only way youll see people play humans more frequently than other races.

Wood Elf has always been a strong choice because 1 extra thing of movement is powerful. That is there biggest + however a +2 dex and +1 wis does give you alot of options class wise currently as not all the races are implimented but in comparison half elf does give alot of options as well. Tieflings are the least appealing personally to me just because I dont really enjoy the race but overall there racials are not bad depending on concept fire damage is the most common damage element overall. Even in bg 3 you see alot of sources of fire damage.

In comparison with other race options with the other races its really matter of class in alot of cases if your not playing and INT based character unless you really want that cantrip or INT based skill checks most likely the Wood Elf will outweigh the High Elf. Same for unless your using a WIS based character shield dwarf in alot of cases will out weight your other option.

Gith and shield dwarves will carry to alot of classes because of armor benefits in early access for power building even with the stat loss. Id even make a shield dwarf mage with as low of an int score as possible because you can off set it with the head band. Halflings you do have the luck trait which is very powerful as an ability there is a reason it is a feat in 5E DND because its powerful.

The biggest push back currently is that wizards being able to cast any spell and being able to change weapons in combat without requiring an action or bonus action takes away from balance I am still hoping to see this fixed as if you let a wizard cast every druid and cleric spell it kinda of takes away from those 2 classes having a purpose. Because if you can just equip an off hand after your attacks in combat consistantly then basically you take away any benefits for someone who wants to Duel wield you just use a 2 hander or bow and change freely at will for the extra attack when you can do it and same goes for a wizard you just cast your spells equip 2 weapons make an attack or cast a damage spell then cast healing word as you need it taking away from those healing classes having alot of bonus action spells that help balance there loss of some of the powerful wizard damage spells. As you do get to higher tiers losing + int or + wis ect for armor becomes less great as your burning feats and stat buffs get that extra stat score racial bonuses are less of a factor at higher levels depending on feats available.

Side note having rolled stats would also play a much larger Impact on classes like monk and barbarian on the melee classes because a barbarian with high str dex con is going to be a powerhouse without armor same with a monk who has high dex wis and con is going to be stronger overall for there unarmored bonus. In case of a fighter having that charisma score to be a factor in conversations while still having a decient range of abilitys for combat becomes important. Adding rolled stats would benefit alot more than changing racials racials are just a minute factor as power increases to higher levels correcting the other things would counter balance this as once you hit 6-8 alot of those racial bonuses start to fade off with the right feat choices. Shadow Touched and Fey Touched Feats can off set alot of ability score losses for casters and feats like slasher, piercer, Medium armor expert ect can off set ability score issues for alot of the melee classes these are things that would make big difference overall in game play and choice for races without min maxing every last thing it would also make adding varient human alot more appealing in early access.

Side note i think that level capping full game release at level 12 - 16 as well would also be a better balance when multi-classing is present currently as the game right now would see more variety with this currently level 20 does hedge out some builds and encourages less multiclassing without alot of thought put into multi-classing though there are some strong builds. Paladin/Hexblade for example or Fighter/Barbarian mixes for critical bonus. Everyone right now is heavy favoring races because low level and other things that need to be corrected to make the game more like 5E DND the largest issues being spell restrictions and weapon swapping which are a much larger issue and should be corrected before the game goes full release or it will cause a much larger imbalance.
