Crusty Old Meatwad (he/him)
It is in actual play, I've experienced it. And then in crunching the numbers, it also shows up. The gap is much smaller at levels 1-5, almost not there. But level 5-10 the gap is much more meaningful. The monks resources just cannot keep up without increasing short rests, and the entire bent of the game is aiming to not be short rest focused based on a couple of class mechanics for good reason - in a meaningful number of games, short rests are just not as available as they are in other games.No it is not in actual play up to level 10. But it seems we have to agree to disagree here.
You talk about balancing without feats as if that's more representative than anything else of tables out there. But I guarantee there are fewer tables that ban feats than there are tables which make short rests harder to come by sufficient to keep the monk balance against other martial classes like the paladin under the 2014 rules. This is a meaningful issue which has shown up in playtest feedback and surveys for a decade now. There is a reason so many players report the monk is lagging, even if they're working well at your table.
