I cannot believe that Larian would be so unilateral as to make major non-optional changes like the +2/+1 thing, lack of variant human or changes to Warlock without showing that to the community first to get feedback, and I hope I am right.
The stat changes and Warlock changes weren't made unilaterally, they were made in consultation with their partners at Wizards of the Coast.
These changes were introduced in the D&D 5e(2024) play-test and both received very positive feedback on their feedback surveys(Over 80%) .
Wait, the Pact of the Tome - we select three cantrips for you thing - was part of the 5e 2024 changes and were playtested?
