[2023] Both LE and D4 could learn from each other

Especially as far as how fun classes are and how good they feel.

Just as a quick example, I think the druid in LE is way more fun and interesting, with a solid variety of different and interesting build options, than the druid in D4 (though, both suffer from feeling kinda blah in the early game). While on the flipside, D4's rogue (both melee and ranged variants) feel 1000% better and more fun than either BD or MM in Last Epoch.
