Yeah it needs distinction, stamina NB after patch will be useless against multiple enemies, just like stamina Sorc is useless against multiple enemies. In fact stamina anything will be useless in 1vX, the only way to survive any length of time is to be a magicka build with Cloak or heals or shields.
Sorc's still , they only lost a bit of their shield and now that everyone will be doing less dmg anyway sorc's won't need to spam it as much so they'll have more magicka available.

I have every character level 50, both a magicka and stamina version.
sorcs and nbs will be the best to escape from a 1vsX (even though NBs can reinitiate a fight alot more efficiantly than sorcs) but i would say DKs will be the best to win one, temps we will see as a lot of skills are under construction and noone knows how ZOS bugs them its hard to predict their efficiancy...
