Newbie want to reroll, which class is not squishy ??

Have a lv88 deadeye with some poor gears (new gamer), very glassy cannon.
Current have 200k+ DPS, all res 75, Chaos 10, 70% EV with 1.8k HP.
For end game experience, e.g. T15 maps, I can clear everything in second, I can finish boss in few seconds too, but literally everything 1-shot me. There are some maps I dare never touch , especially ritual, will guarantee die on 3rd or 4th, regardless how fast I can clear because anything one shot me.
At current lvl, T14 and lower won't give exp, so I can't lvl up, I can clear some maps but will die here and there then lose all exp.

Not enough currency to upgrade gears (to be honest I didn't see any reason to upgrade since it will be the same).

Pretty much done with deadeye, extremely glassy cannon style, end game play need too much intention, not relax.

Trying to reroll other class which is not squishy. I have heard something bad about armor calculation and I think EV is useless as well for end game.

maybe ES build ? Which class is better ? Monk? Wizard ?
