The problem is not the Fighter but the insane gadget and item policy of Larian, coupled with some action design decisions (like Haste). Fighter would be problematic in aoe tasks for example, if there weren't the ridiculous magical arrows all around.
I wonder however why the "casters are sooo bad" whiners hint to the many unfair advantages for melees but forget that lots of mobs are resistant to all physical damage, and the effects of Wet. Partial bias, maybe.
