To be honest Ade, if you find Challenge mode boring and you don't want to improve your Normal mode skill then there's not much left for you in the game. If the only thing that still gives you thrills is findind a once in a lifetime drop but it's frustrating because you don't have the patience to find it, it's not going to help with the situation either. You can stay close-minded and spite on time attack players bringing weak and fake excuses every time, saying this is boring and whichever arguments you will find; it's still the only viable long-term solution for you to experience a progression on this game. By the way, I'm sure we're talking about more than "a few seconds save", there's a real progression to experience.
