3 wins if you win the first. Yes but for 99% of people, they struggle to even get that first win and that is if they don't go against a stacked team or a carry. It could take months for them to get good enough to hit 5 wins if they are running with the same people every time. Which I guess is fine but it is in no way in comparison with the pve equivalent of the raid.

I'm just gonna off purely anecdotal evidence here, but when I first started playing Trials, my warlock had a 0.19 k/d. I accidentally went flawless for the first time on Firebase Delphi back in TTK (I was definitely carried, but they made it seem like I helped). Now I'm sitting around a 1.3kd across the board and 1700ish Elo, for those who care. It isn't because of carries. I actually put in the time and practiced and got stomped a lot before getting up there. I'm not the greatest, far from it, but a lot of people asking for changes to Trials are only doing it because they refuse to put in the work.

Comparing PvP to PvE doesn't make sense in a matter like this. PvE is scripted. WoTM will always be the same encounter once you learn it. PvP isn't like that. There are different players using different strategies and weapons and part of it is knowing how to counter that. Imagine if PvE encounters changed every single time you went into an activity or every time you wiped.
