Oh I too am a solo player. I don't mind being in group dungeons but there are times of being alone and killing bosses etc and I like the challenge of trying to keep alive and do lots of damage. But yes since the recent update and making each enemy pretty much max level soloing most things is not possible anymore. I am thankful that I soloed Craglorn before the update else I would imagine you can no longer do this anymore. I have played a battleground (as per the beginning quest) and it was okay but you are thrown in there with no beginning tutorial so I spent most of the match trying to K.O. peeps where the aim of the game was to move the ball to A > B back to A again lol!
I wish I had max characters, I just having got the time to grind for levels let alone Armour. I have a level 500 something Dragonknight and thats my highest atm. Do you play this on the PS4?
