The legendary sucks but they don't need to put legendaries on PTR for you to test to prevent that. Whenever a power gamer thinks their nitty-gritty nitpicks are more important than not spoiling content, we need to give them a reality check.The solution is simple - they need to not make crappy legendaries. OK let's define that. A crappy legendary is one who has a combat use effect. All the power should be passive and baked in, this isn't some new talent to challenge your skill level. The use effect should be fun and flavour, like a teleport to the raid entrance.It does not require millions of players to balance a damage proc on a weapon. The reason this weapon keeps sucking hotfix after hotfix is because they want it to suck. It's not a mistake. It would have been so easy to bake in the damage passively. It was a choice to make it this way.
Hope other classes gets some kind of legendary weapon.
