Who's to say that the CT system would give you guaranteed loot each week? There is still rng, but at least you could run with whoever you want at anytime and just have fun running BC multiple times during the week. Also would make the armory system useful. Even if you only got 1 piece per week and not per job, the extra flexibility of having multiple classes for multiple groups would be huge.

I think it's a great idea, even if a few people start selling runs, I doubt many will buy. Paying for rng is lol, people only buy Titan cause its 100% guaranteed relic.
