To the OP's point;
Even Gandalf had a sword. He didn't really use it much, but there were situations where magic wouldn't do I suppose. I see no problem in someone having varying degrees of success at 2-3 disciplines, if ICly the character put in enough practice to develop the appropriate talents.
So no, multi-classing in itself isn't a terrible thing (since my char has 2 class skills) but I would refrain from absorbing too many of them into your RP, or adopting the PvE storyline that we are 'The One' because... well, in the greater community RP setting, we can't all be 'The One'. Keanu Reeves would disapprove.
