^removing the mr would be against the general item upgrade logic (that an item upgrade cant lose anything, exceptions are MBR, banshee and some others)

30 mr helps u to survive and u dont need to rush mercs then, or u dont have to go for too much mr since this item+mercs gives already 60 mr and lets u survive a nonfed mage
