The funny part is the 10-15%, i guess you have done some serious statistics study before you came out with those extremely accurated numbers, right? /facepalm Actually i think the devs are considering both PvE and PvP contents for the end game, GG and PvP rewards it's an obvious example.
No offence, but if you are stating that you aren't able to kill a rogue in 1vs1 right now, with a GF, it just make me think that actually you are missing something about knowing the game. That's why i act like that. In the end... i suppose that if you weren't able to win a fight vs a rogue 'till now, you will not be able…
There will still be rogues that are able to 1/2shot you, even after this nerf (with the right buold/gear/playstyle). I hope you know that, otherwise you'll have a big bad surprise. Just an advice.
