i beg your pardon for reviving this thread. but why is reaction is something that didn't work?
"We took the D&D fifth edition ruleset, we ported it to video game format, and we saw the things that didn't work.".
I think reaction is a nice mechanic. They shouldn't have remove it? If they claimed that they took the dnd5e ruleset and ported it over to a video game. Also, while it's nice that bonus action was given to everyone, i think that's not a right thing to do? As i checked the bonus actions only available to certain special abilities, or feats:
"Various Class Features, Spells, and other Abilities let you take an additional action on Your Turn called a Bonus Action. The Cunning Action feature, for example, allows a rogue to take a Bonus Action.".
