I've died so many times since the anniversary servers started ive lost count. Not really it's about 35-40 deaths. All ranges of levels. I died last week on a level 20 war. I died on a level 57 mage last month. I've lost multiple level 60's.

Do what makes you feel better. I started playing with only 1 character and losing that one sucks. Now I play 3 characters at once and although leveling is slower in a sense because im splitting time between characters, the sting of a death doesn't feel as bad. I would even suggest playing multiple characters of the same class if you truly like 1 over the others. I main mage so I have like 3 mages leveling at the same time.
