Simple point. I don’t use concentration spells (unless free use, like that paladins (Tyre) sword in the hands of a battlemaster) at all. And spells that have too many save options. It’s simple, I must do damage to win, so any attack that does half damage on a save or magic missile. I will use situational spells like speak with animal, feather fall, etc. When in battle, forget the loss of action with useless spells, the point is to kill. At this point, it’s almost useless to use other spell types. I also don’t use light spells because I let Gale or my Wizard use a torch. It lights up the whole area for a party and they can still cast spells. Weapons are useless for them now that cantrips are free use. Heck, torches are some of the best in game weapons atm.
Just FYI, there is an exploit. In the cut scenes, if you wake up still in camp for some reason (dream, etc) you can change out a camp companion and get them to cast a concentration spell on you, remove them and leave them behind. The spell stays on you until next rest. They are at camp and can not lose concentration .
