I've thought about this for a moment because of the constant debates about the new Milestone system that was introduced in Season 7. i see a lot of people who are frustrated with their commendations now are seemingly become worthless, or feel that their time playing have become meaningless.
Now, i'm not gonna say that the Milestone system should be removed (as it's been made very clear that the Developers are not gonna do that. Though, i do feel that some parts of the system still needs some tweaks and alterations, like some of the milestones that wants you to be on fire or sleep for a long period of time,) but i do believe an easy fix for this could be the following.
make some of the trinkets locked behind commendations, but make their higher tier versions locked behind the milestones. let me explain.
Let's say you have completed the hunter of the Ancient Terror or Legendary Hunter of the Ancient Terror commendations, well congratulations, you have unlocked the Admired "The Terror from Below" trophy.
however the Cherished "The Terror from Below" thropy is locked behind the Ancient Terrors Vanquished milestone.
same would go for the fish trophies. Like if you have completed the Hunter of the Ruby Splashtail commendation, you have unlocked the Admired Ruby Splashtail Plaque. but you still have to do the Splashtails Caught Milestone in order to unlock the Cherished Ruby Splashtail Plaque.
Sorry if i'm wording this weirdly, or don't make much sense... but the idea is basically that your completed commendation unlocks thropies and trinkets. The Milestones will just unlock some nicer looking frames for those items.
Now, here's something different I personally want to ask Rare to add in that's more related to the commendations of the Tall Tales. please add in trinkets and thropies that are related to those. "Lament for Wild Rose" is nice and all, but i want items that are more personal to each Tall Tale, rather than just one.
It can be Paintings, like Rose and George being reunited or Flameheart being set free. Trinkets, like Briggsy's mask or Sudds Ancient Spyglass. or even Trophies, like a small model version of the Golden Hare or a painted, wooden replica of the Gold Hoarder's Skull.
Ultimately, whether someone at Rare sees this or not, or consider these suggestions, i can't really say. but i can hope. And i hope some of you here might think of this as a possible compromise. But, again, i can't say for sure with those of you who might disagree with the idea. In the end i just hope this is something that at the very least interest some people.
