I get its supposed to reflect ur playstyle, and thats alright.
But u will only play something up to a certian extent. If u start now, u get rewarded - if u alrdy did it, u are being punished, as u either have to skip on the trophy - or try to grind it, which is not supposed to be the idea, but then u will not be able to get the according trophy, and u will miss out on it. And the thing is: u alrdy liked to do it, thats why u have it done alrdy in the first place. And everyone likes to show of their progress, be it on titles, skins, or trophies.
Even if people like to fish a lot there will be a point where its enough, maybe once gained everything (eg. maxed out certain fish types), or once they have done it to a certain extent.
At the same time their playstyle really was, for a long time, to fish constantly.
And now this is not being shown and at the same time, those players feel like getting actually punished for having done that alrdy.
Newcomers who just start the game and do everything for the first time on the other hand WILL get all those cool new goodies with their natural progress.
And the seasoned player, have done everything, having seen everything, will now look like a noob on his ship - or succumb to actual grinding, as, at some point there are only so and so much things u can do anymore that make fun...
Another example: Take the talltales: Most of them u have to do 5 times over, to get the nice stuff. Even if u enjoy playing the talltales - after 5 times its enough.
Again, if u have alrdy done that, u alrdy dedicated ur "playstyle" to that. This is not shown, and if u want to have the trophy for that now u have to do it all over again - or skip it, bec "u dont need it".
Ofc u dont, but thats not the issue. The issue is u feel like being in an actual disadvantage now for having played the game so much alrdy.
So, the "real" playstyle is: Certain person actually LIKES the talltales - but its alrdy played through up to the stop.
So, as a seasoned player i feel kinda left behind quite a bit...
