How do you, like, not be squishy?

Title, pretty much. I'm a level 50 warrior and enjoy tanky characters, so I was playing a deep Paladin build but decided to respec for Battle Monk (charge spam for now) for a change of pace and hopefully more damage. I proceeded to immediately feel the effects of losing Mantle and feel very squishy without extreme investment in the defensive side of the tree. Health regen is basically nonexistent without significant positive IDs for it, and it seems spell spam doesn't really benefit from lifesteal? How am I supposed to stay alive if I can barely heal without using up potions?

 

Try using level 50 health potions.
If you find bmonk too glassy there is no reason to continue with it.
As you'll level up you'll gain many AP allowing you to get a bmonk/paladin build.
In the end, fun > meta

Also get more walk speed :P
