nope, lvl shifts dont really have any effect since they have a scaling code that works regardless which lvl you are
i think the wiki might have some more information on the scaling code GMs use
GMs and Rikti/Zombie invasion mobs are scaled to your combat level. So even if you are Alpha shifted they will still con the same.
I discovered this for myself when a zombie invasion took place in a rather deserted Grandville. Judgement on zombies is fun

Does anyone know if level shifts have any effect when fighting level-less opponents such as GMs or Rikti-invasion enemies?
