Makoa's Dredge anchor will ignore Reversal entirely so you cannot rely on it. You can, however, hide behind walls and geometry and peek to perform one shot at a time, forcing Makoa to eventually retreat due to poke damage.
If the tip of his arrow shimmers, he is preparing an Impaler Arrow. Avoid being pinned to the wall at all costs; his Planted will do 2400 damage before you can even move again, and likely another 2400 to follow, killing anyone.
Maeve's mobility in the air is large but predictable. Pounce is her only way to quickly change momentum, so you can always predict the 2 (Or 3) general areas where she is forced to land.
