Very cool to have reactions. Very cool to have oathbreaker. Very cool to have level 3 spells AND I'M GLAD to see that fireball does not create a big fire surface. Very cool that Minsc and Jaheira are recruitable companions ! (wasn't 100% sure with the article).
But seriously they are so bad at designing a good UI... A point to add about it : These "ask" window are absolutely awfull. Solasta did it in an elegant way with a popup as small as possible. Here it is MASSIVE, it cover ALL the screen. There is one "reaction" PER level rather than a reaction + an toggle for levels. Up the hotbar it is the same... You have ALL reactions so when we'll have level 4 spells, we'll have 4 icons for divine smite and 4 reactions to manage...
Message to Sven : you like to see a character pushing to avoid AOO because you don't like melee character (AND probably because you are not playing your games for hundreds of hours !) It is a huge tactical issue. AOO are a CORE feature of what makes melee character interresting. You made a GREAT step forward when you decide to decouple jump/disengage and make it an action BUT you still have the same issue with shove !
