Recently Blizz's latest PTR patch allowed procs from weapons and items such as Thunderfury to scale with elemental bonuses on gear.
However one of the oddest ones I found to be was Shenlong's, which is supposed to now proc it's energy ball as Fire damage.
This does not make sense, considering that every Shenlong's rolls base Lightning damage.
Further more, it is common knowledge in the Monk community that this weapon set is incredibly underpowered. Compare it to Danetta's, which is one of the only class-specific weapon sets to receive a rework, and it is just not worth using over any other combination of weapons for Lightning-based Monks.
I sincerely hope Blizzard will consider a rework of these weapons, if not just changing the proc to deal Lightning damage as the nature of the weapons implies.
