If you mean see how many merits they have, then that's already there. But if you mean to see what comments of theirs have received a merit, then I don't see the use, and AG3 is doing away with merits.
Because AP won't work as they currently do either, and instead we are going to get a reputation system to award you little thumbs up for smart posting and commenting.
Also, merits are bold and big. You can't miss them if you go through a game's comments.
I don't get why merits have to be 50 words long.What happens if a short comment can qualify for a merit?
They don't have to be 50 words long. They do however need to express some good ideas, things to be elaborated on and how, different aspects of the game and generally act as both a help to the developer as well as a review for the users, while also being comprehensible and interesting to read. At least ideally. if you can do that in 49 words, I will give you a merit.
