Critical Role draws viewers in the millions. My anecdata are contrary to yours, but neither is data. Which WotC has, and seems to be acting upon.
In the live streaming world, 5E seems to be something of the hard, tactical option in the field already.
I don't watch live streams. I tried Critical Role to see what the fuss was about, and I lost interest within an hour. That type of programming just isn't for me, though I realize many enjoy it.
I play numerous wargames and really cut my teeth on 3rd edition D&D (though I started in 2nd edition AD&D). It's hard for me to get in the mindset that 5E is tactical for some players with the core mechanics, that don't rely on positioning or combat maneuvers, which limits magical buffs and situational modifiers.
I guess compared to FATE or Seventh Sea, it's tactical.
I don't want my games to play like Critical Role. I think that trying to encourage groups to play like them and model the experience of a professionally produced weekly show with voice actors trying to entertain millions of viewers is against the roots of roleplaying games. We're not creating radio dramas. We're gamers.
