I could say the same to you. I have extensively used the timepiece (it was my favorite weapon) and know first hand it doesnt compare to the messenger.

This paragraph says it all: You’ll be reloading frequently, with no buff to how fast you can do this short of using Flared Magwell or Pulse Rifle Reload Gloves. Even with Flared Magwell, now you have not-so-great Stability, and the low Magazine Size of 24 to contend with. The slow RoF is a big enough penalty that even with your relatively hard Impact, you’ll do less DPS than the faster-firing alternatives that you could roll with more PvE-friendly perks. Really, the only way we’d recommend using The Messenger in generic PvE content is with a Solar or Void Adept specialization.
