I see you asume much more than i thought...
Comment is not the only way to respond to things ...
Do you for example remember how people were complaining about cantrips creating surface effects? Larian responded.

Technical limits are nice excuse ...
Except they could have make it toggable since patch 1 ... not nearly as well as with curent reaction system (wich Nick himself admited they didnt plan originally at all), but it was totally possible by old togglable passives!
Also ... as far as i know, Larian never comented on their reasons ... so another asumption.
And finaly ... im not aware of any claim that Larian "hate DnD rules" ... so im not really sure what are you trying to say here.
