You're obviously free to do as you please, but I think the change makes RAWK, and this section of it, less fun to read. I don't see what is wrong with having threads dedicated to a specific player (and all aspects at that - be it the latest injury update, the performance in the last game or a new interview), and even though it might be silly and not needed as Mummy Spartacus says above, I think it adds to the site and even experience after the game to praise a player after a outstandning performance, for example. What better place to do that, or perhaps highlight just a single moment from the game - a brilliant pass, a superb run, a tough tackle - than in a thread that is just about a player and not our whole attack or defence? Moments are difficult to discuss, doesn't really spark any debate, but it's good to 'relive' and I can't see what type of thread where it would fit better to post a gif of great goal and/or express your sheer joy over it.
For example, after a dramatic win like yesterday there's still lots of negativity in the post match thread (a thread that is unreadable after a while beacuase it moves so fast), and then I'd like to read a page or two of sheer delight and positivity. Like the soon closed thread about Sterling. Threads like that are perhaps not great debating material, but must everyting on the site be? A few pages of praise and appreciation over this superb talent and his performance yesterday is, to me at least, a nice read away from all the negativity on the site at the moment (even when we win!).
That is just my side of things though, seems like most in here think it's a good idea, but from my own perspective, I think it more difficult to find what you look for - if you're after some news, of any kind, about a player - and like said, just less fun. I realise that you want to cut out all the bickering back and forth between posters, but if possible, I'd rather you dealt with the posters directly than take this step. Those are my initial thoughts, maybe I'll change my mind after it settles, who knows?
