Who even hides behind trees anymore? My nicknames are limited to 3 characters regardless and I very rarely see a random guy behind a tree. Granted it is also winter and you can see through trees, but if you hold down '2' the HP display allows you to see people behind trees... which is still a very rare thing anymore for this change to be happening now.
Causes more fuss than needed. Whoever coded it probably ran into a claymore/person behind a tree and cried.
