On a serious level...
There is an outside world. It has a sun, and grass and you can have sex. It's really cool.
I think you should tell your friend to lvl up to lvl 103 in life until the update. I'm not at all being dismissive of his accomplishment to get to 100, that's amazing but 3 lvls past? That's just manatee fat behaviour, read a book, go for a run learn to cook, go dancing, have some fun, you proved it, you kick ass in Celtic heroes!!!! But come on.. Yer gonna get carpal tunnel and twitch for the rest of your life if you don't just pause your roll.
Judgemental much?
Deuce plays at work on his downtime. Not much else he can do. Im sure he enjoys lots of sunshine .... and as for sex .. well he's married and has kids so obviously he gets him some. Hes a beast and can afk a voidreaper if he needs to.
and as for number of kills.... its what you kill and not how many you kill. He is soloing 5 star reds to get that xp. Clan is sometimes helping him ungrouped so he gets the xp. Plus kill count is only prior to update 2 so obviously if you started before that update its gonna look like your kill count is smaller than say someone who started after and killed 10,000 wolves and crookback runts
