It depends what build/class you play. I have not fuaght many scourge in 1v1 but everyone I have are ofc, condi. I mainly play core s/d thief and even with the ability to port in and out at will, the barriers they use are pretty strong in 1v1's/small scale and become very powerful with support but if they are alone and you have enough dmg they can be focused and bursted down. But they seem to have a bit more condi Presure and corrupts as well than reaper.
