This is one of the problems that creep up when following the "wishlist" method of treasure distribution in the DMG. Character creation is not just "best class for the concept"... but now it also seems to involve finding the best combo of class plus an entire list of specific magic items that best suits. The fact that you plan out a character based around knowing you are getting w, x, y, & z items (practically) automatically, then you get the problem the OP has.
His character concept is not a question of barbarian vs tempest... as he himself says, it's barbarian vs Iron Armbanded, Bloodclaw Urgroshed, Dwarven Weapon Trained, Dual Striking Tempest Fighter. And speaking personally, that just kinda rubs me the wrong way. I am not a fan of character reward being an integral part of character build. I certainly understand how the game has evolved to this point, and why it is a legitimate question for a lot of players who are building characters... but I still can't help feeling a bit squirmy when I hear about it. My problem, obviously... I just wish it hadn't gotten to this point is all.
