Try reading it as in "there's no good way to protect yourself against melee" and maybe you'll get it. Hit a caster and he won't survive unless he words out. If we're talking about a sorc, he'll usually be behind a pet and a charm. Well great. Kill the pet (that won't take long) then you've got easy access to the sorc. Most warriors carry healing potions to help against that pesky little charm stabbing here and there.
But who knows, maybe pets are actually very hard to kill with a well-enchanted battlespear, and the caster might actually get lucky and get charm spell off on whoever is attacking, only, damn, well enchanted armor that takes care of your magic (unless you're a giant getting charmed
).
Edit: Yes Gilgon, but we're bound to get more sensible people arguing sooner or later if we continue this long enough
