Are players who are taking these feats aware that they are taking spotlight away from other players? If so, why do they continue to choose these feats, or having taken them, choose not to use them to act in service of making other characters shine from time to time?
Is this a case where we must change the rules to save players from themselves? Or might we expect they'll voluntarily make choices that don't overshadow others to the detriment of the game experience?
The feats just don't fit in 5e.
The monsters aren't designed to handle them, and other classes aren't designed to compete with them.
They're a mistake to be there.
It's not about players wanting to overshadow other players, it's about those of us who came from 4e/3e where you needed to take such feats to be effective, then finding around level 10+ the game really isn't designed with these combinations in mind. That's a good 8 months of investment of time potentially ruined.
