There's still some people, but all they play is G rank.
Which is inconvenient, as I started a new file.
I was just on last night, helped a pair of HR4 and HR5 guys. In any case, I've long been HR9 but the best fun in the game comes from sandbagging it and taking on Low/High Rank fights with joke weapons and armor in multiplayer. Like I said before, I'd be glad to hop on, just let me know when you want to get on so I know when to look for you. --- Don't get hit and hit it until it dies, in that order. Kill it, carve it, wear it, repeat it.
