Mod Note:Thus the quotes around wrong. It's not wrong to play what you want, but if your character under-contributes because it is mechanically inferior, it's bad for the whole party, and even for the campaign making it harder on the DM. It's not wrong, but because the game is imbalanced, it's 'punished.' (There are those quotes again: as in, it has negative consequences. Not as in it's meant to correct an unacceptable behavior.)
There can certainly be instances where a player wants an inferior or under-contributing character, but a balanced game would allow that to be done advisedly, and without dictating that only certain general concepts could be that way D&D-like games already have level as well as class, so, even in the nearly unprecedented case of balanced classes, a player intentionally wishing for an inferior character in a group and with a DM both willing to work with that, could simply play a lower level PC than everyone else.
That is increasing imbalance. What you are saying, and you're not wrong, is that sub-classes are imbalanced within each class.
Each choice the game presents must be balanced with it's alternatives. Races should be balanced with other races, classes with other classes, sub-classes with other sub-classes w/in the same class.
Imbalance tends to make imbalance worse. Class, especially as you level, is by far the most significant choice you make for your character. Classes are imbalanced. Sol, yes, an inferior class may well benefit 'more' from choice of race or feet or background - in a relative sense, since it has less going for it, any improvement is bigger proportionally.
Perfect balance is impossible. Less terrible balance is the only plausible goal without re-writing 5e from the ground up.
One mistake classic D&D made was trying to balance classes across all levels.
Since all classes use the same exp progression, they should balance at each level.
Balance is all about choice. Improving balance means more real choices.
It is a bizarre feature of 5e that no class doesn't cast spells, yes.
None the less, the issue of D&D making non-supernatural characters profoundly inferior remains, with the handful of non-supernatural sub-classes being inferior to their supernatural counterparts.
It would be cooler if you didn’t load your response with value-laden judgements of other’s’preferences.
