Some things that i think will be good for balancing pve mostly on m10s.
Remove hatchet ability to hit multiple targets, it will be still the best weapon to kill bosses but not that better than other weapons on clearing expeditions. Same for all ‘small’ weapons that comes in future.
M10s should have 50% heal reduction by default. Use your pots, dodge, life steal and positioning to survive, not just a mashing of left clicks while the healer do all to keep them alive.
Lower mobs magic resistance to make magic weapons more viable.
25% freedom and/or grit on mobs, some expeditions are too easy with hammer or spears.
Bleeds and poison does double damage, DoT builds are fun.
Arrows and bullets have at least 1.2 multipliers (1.4 with orichalchum) on expeditions.
Mobs that apply rend, use more aoe attacks and roots.
Remove perks from shields, or at least leaves only wards, sure footing or defensive perks.
More mixed mobs, not sections with differents types of mobs. Maybe only one unique type of ward and bane modifier.
Higher cap on rend
Mutations that applies 10 stacks of bleed, that only goes away when you die and respawn.
Double the expeditions weekly limit.
Let we all know the player best time,
numbers of completions and any relevant achievement on expeditions lobby, this will make groups to form faster.
More random mobs on m10s and not only pre built.
Aggro should change faster
Headshots with double damage
Selling umbrals on market
Mutations with mobs who resist to physycal damage.
Damage of ranged mobs are too high.
Some random buffs to be found that last some time.
