Easy way to get experience in City of Heroes? (COH)

I ran across an interesting way to get experience today in City of Heroes. I was running through independance port with my 12th LVL Tanker and was trying to dodge all of the 23-26 lvl bad guys. I got a little too close to a couple of said bad guys and was attacked by them, but kept on chucking and made it through the zone without a painful death.

A few minutes later I got 70XP and 70 influence, apparently someone else killed one of the guys who had hit me along the way. I'll have to try that again sometime, see if I can reproduce similiar results...
