Concentration seems to be more of a hindrance in this game than i think it is meant to be because of a few factors.
First, I have a real issue with Larian turning a couple of status effects into "miss turn, break concentration", when they are not supposed to. Prone should not break concentration, stun should not break concentration, you can still concentrate and have a limited turn when you are stunned or prone, but not in this game it seems. Things that do break concentration: being downed, being incapacitated, casting another concentration spell, failing your con save upon taking damage.
Stunned, like Paralyzed, includes the Incapacitated condition, so it does break concentration in tabletop as well.
