I tried to do some boosting via a low level dungeon, toon "A" level 18, toon "B" lvl 90
just the 2 in ragefire chasm, the lvl 18 got zero xp when trying to run him through.
did something change with regards to boosting?
Now, it's fair to mention that they are on 2 different servers/bnet accts, but that shouldn't matter.
