D&D 5E Best feats in Xanathar's Guide

[Horwath]

Still the main problem with 5e is that feats and ability boosts share "character slots".

That way a feat HAS to be very powerfull to overpowered to even be considered over +2 to primary. And as most campaigns end around 10-15th level, that leaves 1 or maybe 2 feats to choose.

With that limited amount of feat "slots" only the best of the best will be chosen.

From XGtE that leaves; Elven accuracy(for classes that can force advantage every turn), Orcish fury and squat nimbleness.
Drow and wood elf magic would be in this list if they are "half feats".
Fey teleportation would be also in if it would add; once per long rest you can cast dimension door at 7th level.

There should be extra feats added to character development.

at 1st, 5th, 9th, 13th, 17th and 20th level a character should get bonus feats. That should be feats from this book and skill feats from UA.
And any feat from PHB that is NOT: Crossbow expert, Polearm master, Greatweapon master, Sharpshooter, Resilient, Lucky, Spell sniper, Heavy armor master,

Only if your primary is even-numbered. If your primary stat is odd-numbered, then any feat which gives +1 to that stat is better than +2 to that stat. That's why so many of the feats in Xanathar's are "half stat" feats.

As I noticed, most people use point buy or default array, so any odd primary/secondary ability score is intentional for 4th level pre-picked "half feat".

And half feats would maybe be more picked if they were +1 to ANY ability plus whatever the feat gives.

Also the option to take 2 "half feats" without any ability boost at once.

Also, even the half feat has to be strong enough to replace that lost +1 to some ability.
