Hardcore Help Please: Easiest class to beat campaign this season?

Last season I used a Blood Mage to make it to level 78 in HCSSF before a skill issue ended my run, it was incredibly fun. This season has been a total nightmare. I think I'm on my 12th character, the furthest I've made it was act 3.

What is the easiest class to beat the campaign?

I'll play anything, build guides are welcome.

My impressions:

Monk seems impossible without using a bow. The damage of abyss monsters vs any evasion based melee character is just hopeless. One time I leveled to 30 with a Monk using a bow, respecced to hollow palm and was immediately one-shot by an Abyss monster.

Witch seems strong, ES/Contagion worked the best of any build I've tried so far but it still felt crazy squishy.

Ranger is definitely super strong because you can just hang back and nuke. Still, it's super squishy, if I play Deadeye again should I be going Armor/ES instead of Evasion/ES?

Warrior felt strong but not at all fun to play. I played rolling slam/bone shatter through act one. Still, melee feels so squishy in Abyss which sucks because I want to do the content. I try to stack as much armor/life as I can find.

I don't know about campaign but the most played endgame class in HC this season is Lich.

I played a lich last season and they were very tanky. I can't remember when they really started to shine. I have taken every class to end game and the lich was the tankiest character I have played.

A warrior is probably pretty good in campaign. I did not play HC but my warrior died about 3 times in campaign with me not being very careful. Deadeye are very popular for their clear speed but they are squishy. My deadeye died a lot in campaign.

Reading your playstyle I think your best bet is going to be crossbow mercenary with hybrid evasion/armour.

Get a lot of deflection and some % armour applies to ele dmg and you'll feel tanky, and it's naturally a ranged class.
