I gave Shadowheart War Caster so that she would stop losing concentration, but now it's just more annoying when she does. :P

Playing on balanced, I haven't had too many problems with breaking concentration. Seems like everyone's pretty good at rolling those saves. My main issue with concentration is just forgetting that one of my characters is already concentrating on something.

Technically not our POV, maybe our POV when a teammate is concentrating? :P

Warding Flare, Shield, and an AC of 18-23 can negate this problem most encounters even at early lvls.
