In my only 5e campaign, out of 8 PCs, one is MC - wizard took one level of cleric because he thought the party had too few healing resources. Based on how this has played, in future campaigns I am thinking that I will disallow 1 and 2 level dips unless the player has a really, really good RP reason.
Yeah. I just don't like that my vote for rare could be misconstrued as a vote for disfavored. My table likes multiclassing but we don't do it too often.
But I also don't want to hijack tge thread (I find I need to say that more often than I ought to!)
Not to sidetrack the conversation but if they had asked would you have allowed them to replace those classes with new selections or required then to stick with it.Of my 4 groups, we've had 2 players multi-class. Both were unhappy with their original class selection.
