What was the topic again? Oh yeah. Reactions like Solasta.
I must say that the argument that this is a turn based game has some strong merit. This is NOT an action hack/slash game nor RtwP. Thus, you are not meant to have super fast combat. Turn based is supposed to be strategic, like Chess. Sure. We all want faster combat so that it's not boring watching tons of enemies slowly taking turns. However, that should not be at the expense of strategy.
Reactions provide a strategic advantage during enemy turns. They are meant for a player to have things they can actually do during an enemy turn. Take away player control of Reactions means players once again have nothing to do during enemy turns, thus defeating a primary purpose for Reactions.
