I forgot to say abyss walkers are actually the best in pvp.
without them in the game, ravens would be the best in pvp. because they are easy to do combos and the base damage is a lot. ravens are similar to windwalkers but they just have more damage.
so it is like assassin subclasses keep each other off limits to be the best pvpersin the game. but abyss walker is just the better option right now.
lf is also pretty good (due to the bringer's skills kit), and you can even beat raven/ripper but it is like if you need 5 combo to beat your opponent with abyss walker, then you need 8-9 combo with lf because his damage is generally lower.
