I disagree, just like we have achievement rewards that dont take inventory space but you can buy things with, this system would allow for the same thing and even if youve bought everything you would want to keep earning them for things that may appear in the future patches. Also, in casual content there are very few things that can stop a good player from performing well TBH, Personally I have never been in a raid or instance where I feel other people have hindered my ability to perform well for most of the raid, have others killed me on accident? yes. But have they killed me on accident every fight that raid? no. And if they are new, thats okay, they will gain experience and perform better next time to get the medals. Its not the end of the world if you dont score one on your first run ever.

No need to make them encounter specific, just to regularly add things so people keep making sure to score them as they go about their daily activities.

Likewise I would counter the current system rewards players that AFK and farm others efforts for the clears, and in most raids people don't loot or are reluctant to kick others because their offenses may not be severe enough to warrant it, whereas the other system rewards people and may make new players interested in becoming better.

But it is a difference of opinion and I respect that. It may be a nightmare to code, it may not, SE already experimented with grading peoples performance for Duels in Bozja and adjusted it recently I believe, so they are open to this system.
