I think it's more about proof. The road to the clear is the most important sure but having something different to remind that you made the effort is nice as well. The reward doesn't have to go far, no one complains about ultimate weapons lol and i'm sure some of thoose raid got easier with time (but at least it's not newer ppl just going in braindead just for the loot).

I understand the frustration tbh but hey don't say no to ppl who don't want to try and their defenders, they don't want you to get more unless you go to ultimate (witch is quite extreme imo). They'll say everything will become worse without trying to find an option.
