“You can do fine without it” is a pretty poor excuse to not take a game-changing ability.
The willful ignorance of just how strong Iron Hook is for PVP by the swordsman community is a bit baffling.
I don’t care what build you are. If you can fit corsair1 in your build, you will do much much better than any other swordie who doesn’t, mount or not.
Landing a hook has a number of benefits:
1.) it goes through all status immunities currently in the game.
2.) with chain attribute you can CC up to 3 players at the same time.
3.) with chain you can reveal the location of any cloaked unit, simply by hooking their pet. This works wonders vs hunters and is a hard counter.
The only build that can’t fit it imo is sw3cata3goon2, and their playstyle is centric around tagging people with dethrone, and picking the correct time to rush. If dethrone and rush are down, they are pretty much useless.
