No real time elements in the turn-based section of a turn-based game, thanks.
After much discussion on this thread about RT elements, it just wouldn't work, imo. The camera is in no way equipped to handle that, AND it would make laggy computers super hard to manage reactions.
Imagine it. Enemy mage casts Fireball. Lag. Camera is still on the other side of the battlefield. Wait. He's what? Tries to hit RT Reaction button. Too late. By the time you even discovered he was casting Fireball, it was too late for you to use Counterspell. Now, half your party's dead.
Yeah. No thanks. I'll take Solasta popups any day over that. They really aren't that bad, and if Larian improved the Solasta concept, popups could be VERY smooth and unobtrusive.
