I have Awesome set upgraded to 80 hp and speed. Normally I can handle with one sniper hit... but sometimes no. Why? If sniper deals 2063 dmg and I have 2080 hp so I should have 17 hp left, but sometimes I can be killed.
Additionaly I don't know how it's for other sets, but I can't wear head and back accessory like it was in MV. There should be possibility to upgrade accessories in set
