Your first argument amounts to "My definition of greatly is different from yours." Your second argument fails to recognize that BLU will probably gain MAB options, which ultimately undermines the capacity of MAB Swords. While it is possible for swords to beat elemental staffs, it will have to do so in an environment where 1) It currently does not, 2) The bonus from staffs is likely to remain consistent, and 3) superior MAB options will undermine the utility of MAB swords. It's a very speculative argument at best. This is before considering magic accuracy associated with staffs.
