This season has been a banger so far EHG and I’ve thoroughly enjoyed my playtime so far. However, I believe there is a significant issue with certain classes survivability at endgame with the current corruption scaling or class defensive balance that needs addressed.
As a Bladedancer (rogue) player, even with high investment I’m having trouble pushing 2500-3000 life. Even with 60+% dodge and a ton of leech, there are too many things one shotting at relatively low corruption (~200). Anytime there are multiple dangerous mobs on screen, it becomes almost impossible to dodge all attacks and ground effects. This is compounded with certain skills and playstyles such as Dancing Strikes, which has long animations and moves the character in imprecise ways. It also requires an attack to land every ~4 seconds to maintain the rhythm buff or damage tanks. It’s not feasible for this character to hit and run with the current design of skills. I had similar issues with a Multishot build, which requires melee range to maximize DPS. Marksman just doesnt have sufficient defensive layers to make that playstyle feel anything but clunky to play as corruption goes up. Again, this problem shows up as low as ~200 corruption. I don’t need to be able to face-tank everything, but how frequent the oneshots are for this class at low corruption with moderate defensive investment feels bad.
Seeing videos of things like void knights playing with ~6k life pools and face-tanking Aberroth while pumping damage, it’s clear that something needs done to improve the survivability of other classes.
Suggestion: post a link to your build on lastepochtools.com. You can import your character from the servers or a save file. That way someone will gladly take a look and help you.
There are videos of Rogues clearing higher corruption and defeating bosses, so if others can perform what you have issues with, then most likely it isn’t an issue with the class lacking something, but rather your build lacking something.
As for Health, it always comes down to investment. You can do a quick check. There are 6 health affixes:
This is just on your gear. You can have up to 22 gear affix slots allocated into health. How many do you have? In the link from Llama8, I can see 7, and some of those aren’t even T5.
You’re also quite heavy on the uniques. If you could switch a few affixes out, your resists would drop a small amount but you’d get an additional 1k hp. Plus you may wish to swap your weapons to the other slots so you get some parry chance & unless you’re blinding everything, you may wish to get either capped crit avoidance or more crit damage reduction.

Sentinel is FOTM much like, say, Lightning Spear Sorc was in one of the Diablo4 seasons.
I guess that after the season ends, he’ll be nerfed, and some other class/mastery will be buffed to FOTM status by the developers to promote “something fresh”.
This is a common strategy used by developers to shake up meta, invite people to return for another season and try something new. There’s an additional bonus for MTX heavy games: you’re likely to try a new class and skillset, and you probably didn’t buy any MTX for it, so you’re more likely to purchase it for a different class than you’ve already played.
This is very deliberate and has nothing to do with incompetence of the balance team. It’s a business decision.
If you like Rogues, I’m pretty sure they’ll become FOTM eventually.
As for your character, you simply lack defenses. Your EHP is low.
Even my crappy Sentinel with ~1200 HP has around twice your EHP if we factor in the effects from five sigils (they don’t show up on the character screen unfortunately).
Or maybe there’s 15 classes in the game, so EHG just can’t quite get to buffing every single thing that needs it each season. 
Maybe. But since it’s a common tactic for modern ARPGs to shake the meta, I’m inclined to believe we’re going to see the “FOTM” class/build each season.
