I find myself in a similar position. I used to want all of the aggro that I could get because, hey! Free spell points! Also, it was often better for me to have the aggro than a self-described tank because I could self heal far better than the DPS melee who called himself a tank could.
After U14, I still wear the Torc because I still like getting SP from being hit and I still get hit. The only difference is that I no longer actively seek opportunities to get hit. If someone else wants to take those hits, I'm glad to let him. I know I'll still get hit often enough that the Torc will be worth wearing. ...at least until I find a specific item that makes me seriously consider giving up my Torc - and I haven't found one yet. Even without "Torcing up" by letting enemies hit me while I wait for my blue bar to grow, I still get a very nice number of SP from the hits that I get naturally as part of running through a quest.
