I used to feel the same, but looking at where the mechanic is actually used, everything printed into standard has ward 1, 2, 3, discard a card, or exactly 3 life, preportional to their cost and color.
Iymrith, Desert Doom has conditional ward 4, and I've already explained why I love that
TECHNICALLY there is
The Tarrasque, but at that mana cost and requiring casting it you deserve hexproof.
Other than that?
Octavia, Living Thesis (8),
Neverwinter Hydra (4) &
Winged Boots (4, and how is this a name that got used in 2021?) are all EDH only, where occasionally you'll get people with 35 mana lying around, so we're safe.
So, no. hexproof and protection and all the mechanic that piss people off like this ELIMINATE the ability for one player to interact, they don't reduce it. Ward is specifically interesting in that it reduces it, but not all the way, evenly across the board.
Ward reduces interaction like
a creature being black does, or having 4 toughness.
Also telling me flying creatures are worse because plummet exists is peak internet technicality. There's situations where
lightning bolt is worse than
shock too, but nobody operates this way.
Protection also has nothing to do with your deck, and everything to do with your opponents deck.
