How is Burglar's leveling experience?

Never played Burglar but slightly tempted? I am curious to how it plays. I was thinking blue since it relies less on stealth than red does. How does it handle in enemy camps? I know it's an excellent 1v1 but sometimes you can thelp but 1v3 at times. How does it fair? I'm also a solo player, so I won't have any friends with me.
