A valid opinion, but not shared by everyone. Supporting both would be a better choice [...]
If they do support both, then they should design the game around RtwP-combat and then slap on a turn-based mode similar to what Obsidian did with Pillars of Eternity 2.
I like turn-based RPGs (check my tags), but I have zero interest in playing a turn-based Baldur's game. I am sure that many others feel the same.
