No love for scepter?
Scepter is a bad group pve weapon, more specifically. The main issues with bleeds stacking and all condition builds are the stack cap and the ramp up damage. First, you can’t put more than 25 bleeds, one burning, one poison on a target. This isn’t noticeable in solo, but in a group content, many direct damage spec will also apply damaging conditions via on crit effects or burst abilities. For instance, my assassin engi will keep 20 bleed stacks on a boss, burning, and poison if i decide to use it. That means your damage will get reduced by a lot, since you rely on those conditions to do the damage. Secondly, the ramp up: conditions are slow. It takes a while to reach your maximum dps by stacking the maximum amount of conditions. During that time in an organized party, most mobs are already dead.
The implementation of sinister’s stats may see the rise of one single condi player in all level fractals, but I highly doubt it. There’s also smaller issues like the damage on objects and the number of cleanses available to bosses, not even speaking of condi reduction.
