My fighter, who is by far my most valuable toon for this raid, needs ABSOLUTELY NOTHING from tower. He has every ring he could possibly want and luckily got them kind of early. I still run it twice a week (though i'm taking two weeks off to TR my main) because my friends need rings, trophies, and chances of not getting +4 tomes.
I don't consider getting my friends/guildies equipped to be a burden, neither do the rest of the people I run with.
