it depends what you're looking for
if you're doing it for fun and enjoyment, then yea go for it
i'll tell you are wrong if you're looking for efficiency in grinding or pvp/gvg compared to a mage that uses skills to kill
there was a thread on the official forums where someone was arguing that a melee mage has in-game advantages over regular mages
i responded to all of his points, and it turned out that the only argument he could really support is that melee mages are fun
if there's ever a skill that makes mages not be blocked, then hell...yes...
but there isn't
and yes, if you have any questions about how a melee mage turns out in the LONG RUN, you can ask me
