so...like the title says who do you think would win?
magic: i know this is really broad but consider all things magical like mages, warlocks, demons, dragons or undead.
science: guns, bombs and planes. medicine vaccines and what ever else.
neither side has win button like "lol the plagues owns everything" or "we make a virus so all magical things die"
edit: here is a scenario
the alliance and dalaran wizards allied with the night elfs and their armies and the horde march towards a combined army of present day military.
who would win? bombs and bullets or fireballs and magic swords?
edit:2
some people here are doing what i was afraid of, magic HAS limits, you don't see magicians in any novel or game casually lifting mountains and blasting nukes from their palms. from all the fiction books i have read magic has to do with the person's stamina and concentration. imagine a WoW mage do you think he has limitless power?
