That particular comment in that article is certainly the source of a lot of doubt building towards BG3 both from fans of the previous BG games, and from D&D fans in general. I think it would be in Larian's best interest to address these concerns as soon as possible in order to stop the spreading of the negativity that's caused by that comment.
You are right,
but for Larien, even leveling is too slow Dungeons and Dragons’ leveling system is too slow for Baldur’s Gate 3

"i love soccer, wanna make an soccer game, but the rules that worked on fifa, pes and etc doesn't work, so i will re write the soccer rules"I love leveling on D&D. On my solo max difficulty Dragon Disciple run on Icewind Dale EE, i goes from running from Goblins that succeed on their saving trows against charm to stopping time, conjuring an Efreet army and etc. On Might & Magic VIII, goes from an weak necromancer that barely can conjure two toxic clouds to an badass lich that can reanimate dragons, teleport, become invisible, or nuke cities out of existence. That is amazing.
