I'm all for Trials coming back(despite never playing it), but I'm far less on-board with that idea when there isn't a good enough PvP sandbox to support it.

Last Word still kills in 4 bodyshots, which I think needs some tweaking. It's even banned from official tournaments because of it.

Lord of Wolves is back in the meta, and is really making a case for backup plan fusion rifles such as Erentil and Wizened Rebuke to stay in the meta.

Primary weapons in general(with the exception of TLW) could use some minor buffs to bodyshot damage to make them more relevant, special weapons are much stronger than most primaries currently.

Luna's Howl and Not Forgotten should be reassessed in my opinion as well. The nerf was moderate, but I think that in a game where Last Word kills in 4 bodyshots, LH and NF should be 180rpm again. In that scenario, Magnificent Howl can function as it does now. If LH/NF stay as 150rpm, then I think Magnificent Howl should increase precision damage again.

I could go on, but you probably get my point. Trials potentially returning is fine by me, as long as the PvP sandbox works.
