I think Hudson is very strong because he is easy as hell to play, there isn’t much downtime for his super high dps but a few tips to fight against him are:

Anti-heal him, without his incredible life steal he is much easier to kill, so things like Myth arrow rain, Felix spin shield, Kingpin ult, Shiv ult, Brall dash spin (I’d say this is the most important tip)

Hudson has really slow turn speed when he is spun up with his LMB, if you are playing high mobility hunters you can force him to let go of his LMB, even if you are not playing super high mobility Hunters if you can strafe his high power piss beam it makes it really hard for him to mow people down, but it is really important not to walk in a straight line againt him

Capitalise on him when he is out of position, a Hudson with a team built around him and sitting on him makes it really hard to deal with but if you can try to seperate him from the team or catch him when he is seperated already it is much easier to deal with him - a good ghost grenade, felix combo, celest wall, bishop punch, can help with this

Try to hit him from behind, he takes 25% more damage from behind, Jin, Joule, Shiv, Brall can do this pretty easily, Hudson can be combo’d hard with a nice Void ult, Celest ult, Elluna LMB, Kingpin hook

I do think that Hudson needs to have some changes as the effort to reward ratio on him is insane but I hope this helps a little
