Hopefully that wasn't taken as a slight against casters or an underestimation of them because naturally all classes are fantastic grin

Just didn't want the OP to get the wrong impression that they're required as some here are implying, so had to use my own experience of not having any in the party as an example. Game can be beaten on any difficulty with any party composition without any issues as long as one knows what they're doing, which is a great thing because if the player had to follow a certain meta to play Tactician or Honour Mode then it would be a terribly balanced game.
