The first few levels of DnD kinda need to go by fast. At level 1 and 2 you have so few HP that it's extremely easy just to die from being unlucky.
It's not just sparing to the player a quick death, either. The early levels are notoriously... Lacking in tactical options, which makes them vaguely unexciting compared to what will follow.
It's almost universal opinion that D&D is at its best in the range between level 5 and 14, with the lower end being "where classes start to come online" and the upper one being just antecedent to the point power creep starts to break things a bit too much.
Incidentally that's more or less where we can expect this game to end, given that Larian already confirmed their intended cap is NOT level 10 anymore, since it turned out they had too much of an overabundance of content to stick there.
