Are bear defences bugged?

This is gonna sound incredibly tinfoil hat, but I really wanna see if anyone has experienced this.

Me and some friends are playing bear on different classes (as an example, I'm playing smith of kitava), and we've all noticed that the bear is squishier than you'd expect from an armor character. This makes sense since you got no shield, but what REALLY feels odd is how powerful fire damage seems to be.

Early in the campaign we'd all die to random ignites and in the later acts and interludes it always feels like we die to either fire or phys damage, regardless of our resistance or armour against elemental. And again, phys could be a lack of shield situation, but I have no idea why fire feels so strong. So if fire damage from enemies hasn't been buffed the only thing I can think of is that some of the bonuses of bear form may be bugged and you actually take MROE fire damage than you're supposed to? I've looked at everything I can think of, from passive skills, ascendancies, gear, weapon, quest rewards, mobs, environemnt, zone and character level, everything you can think of and it still REALLY feels like the bear is awfully succeptible to fire damage for some reason.

Def, im running only bear and 1 hit from white mob im like 50% down in hp

it need to be looked at
