After a while of pondering, and also the fortune of parting shot being banned on ladder due to breaking the games, I was able to come to a conclusion on parting shots presence in the meta.
Now parting shot was something limited back in the prior generation when trademarks could be run as many times on your team as it wanted because you could basically reduce your opponents stats to an absolute low then send in your setup sweeper with complete safety.
Now that it has been limited it cant directly cause this without a few specific circumstances as some have shown. However, that isnt the reason I feel it needs to be banned.
After trademarked was given a ladder, it was not long before many how found various loops that could be abused alongside other trademarks with parting shot, such as wish, substitute or kings shield smeargle. There is even a team posted earlier on in this thread showing a gimic done with simple beam. Parting shot makes it extremely hard for you to ever break your opponents team as they can reduce two of your stats and then pivot out into something that your mon will be no longer be able to break after being debuffed, all in a single instant. You could even run one mon with a trademark that drops atk and one that drops spa alongside it and essentially prevent ur opponent from ever taking any major chunk out of your mons unless u run focus energy or laser focus as trademark. Parting shot provides more safety to switching in than anything ever should and especially in conjunction with other trademarks. And in all honesty, despite my request and especially after wading in and out of the server, there doesnt seem to be any real opposition to it leaving or any wants for it to stay outside of people wanting to abuse it themselves to their opponents displeasure. That and it was already breaking games as is cause of infinite loops lol
So to rap this all up,
Parting Shot is now
BANNED as a trademark. tagging
The Immortal , though its already banned on main anyway, so it can just stay that way.
Now I also heard people complaining about substitute. Substitute I would rather wait at least about 3 days to see how it fits in the meta and properly see if many are considering it bannable (also dont wanna go on a ban happy run), at which I would rather hold a suspect for it. I would like to at least see feedback on it over that time and replays showing it being broken, as Im not free most of my day to confirm for myself and Trademark lacks a council as of the moment.
Nonetheless, thanks to those who read and are playing trademarked, any feedback given is greatly appreciated. Hope you all have a Blessed Day :D
