personally I wouldnt be disgusted at all. I never had the intention of going for completionist on my main, but I have collected 6 past lives to supplement his skillset. At this point I'm collecting some of the epic gear I've missed out on the past couple months. I would be tempted to TR again after I finish crafting to pick up a few more lives BUT I'd never consider it unless theres a change to the system.
I would applaud a change. not mourn the time I wasted in previous lives had I waited.
