If you feel it's abusive, just restrict it to swapping like for like - i.e. you can swap weapon profs for different weapons, but not skills.
I am unsure what I will or won’t allow from this. I started off really stoked about mix and match features to make custom characters and feel a bit let down by this... however I am not the only DM in group (we play twice a week my game once and the other two alternating) so I don’t even know if this IS for my game... especially since we just hit level 6 and expect to go for many months...
My takeaway from the video was that the +1's and +2's for specific attributes have nothing to do with balance. Dexterous Elves are not dexterous for balance reasons, but to hew closely to the tropes and stereotypes of elves in fantasy literature and gaming for the past few decades. So it breaks nothing to allow players to move those bonuses around.
A relatively small problem from WotC, who can do no wrong.
What brought that on?
I think most player are still going to have an image in their head of 'what a dwarf is', and it's not going to be tall or nimble. The tropes are a lot stronger than an optional rule in one game. So you can still play against type - you just no longer "suffer" mechanically for it.
I'm not sure I like that. Then people are picking backgrounds just to min-max (even more so than now). Frankly, I like the idea I've seen posted elsewhere of just getting rid of the +2 bonus for race, and apply it directly based on class. That's really the end goal anyway.
