As others have said,rushing Blows are now only from bosses that are +4 levels (KaraT raid bosses are only +3 levels) so 102.4 is no longer a "mag number". 490
Defense to preventrits is still a mag number for the few days that you will still be 70. This wow.allakhazamomdbitem?witem=34675;soue=live is stillonsidered to be one of the best Paladin Tanking shields (until you get a better one from raids or WOTLK anyway) so if you have (oran get) the SSO rep for it, get it. If you have badges to spend, upgrading your gear isn't going to hurt at all, it just isn't going to last forever (maybe level 75-78 at most), but at this point, you might as well spend your badges on something. I would rommend the 60-badge ring from the SSO badge vendor (the smith on IoQD or the SSO badge vendor in Shat next to the portal to QD). Rings are tougher toome by, and the 60-badge ring is better than the violet-eye exalted ring from repeatedly doing Kara, and is also better than the tanking rings that drop in Kara. With yoururrent stats, youould easily run 3-6 heros per night with a dent group (assuming you have the time) and upgrade whatever you want to before the expansion just for fun. It won't last you forever, but it WILL make the first 5-7 levels of WOTLK even easier. Primal Nether and Nether
Vortex and Badge Gems are getting dumped on the market likerazy while people blow their badges now, so you might as well just get some better equment to make levelling even easier. I plan on loading up on whatever badge gear that I am missing over the next week just bause I am having fun mauling heros now.
