Whether the PC cares or not, I still believe the answers to those questions should matter in the campaign if the player chooses to play a character who gets their power from someone else.
Funny how all those options mean the patron isn't important in actual play at the table and functionally mean they have no effect on the PC other than being the vague source of their super powers.
No thanks, personally.
Why did the PC enter the pact? And why did the patron? Do either of those questions matter in the campaign? Any warlock in a game I run is going to be affected by the answers.
It shows that WotC feels making a book that helps new GMs is more important than making a book experienced GMs might want to give them money for.
Buy the TotV and/or A5e DMGs, and skip 5.5.
No, and honestly I would like to see the fighter as literally better at fighting too. But no game compatible with modern D&D will ever do that. This is why I also play and love the OSR.
