People keep misinterpreting this so badly that it became hard for me to see the actual flaws in this.
Having torches everywhere won't do anything negative to you, (...)
Actually it's you who don't understand. Yes, it's true it "won't" do anything negative to have already explored all those areas and looted all those chests with normal "malus" torches.
The negative is ALREADY done ! That means everything he has explored, every loot he took, every death he had, he could have very probably had much better loot, and maybe not die as much from bad luck, missed crits, and dual damage rolls that crippled his dps because game decides to take the lowest of the 2 since he had "bad luck"
The damage is already done, and he, as most of us so far, knew nothing about it !
We all got blind-sided by this, and actually nothing in the games even plans to tell you anything about "luck" until after hardmode when you get the wizard ...
So it concerns every body, not only those who "misinterpret" the mechanic : everyone get bad luck without knowing it, get worse loot, worse damage, worse RNG in everything they do, actually, and they have NO WAY of even knowing it until after hardmode, which for beginners will maybe never even happen if they quit the game before that.
I know in my case, it took me years before I played a single world far enough to discover there was a hardmode.
Also I have to reply to your last bit, because it makes absolutely no sense

That is a really bad idea, you can't have such a massive reward without any sort of trade-off.
Having luck without bad luck would be essentially re-logic just doubling the drop rates of everything in the game by default, it would make everything extremely easy and unrewarding.
I mean, what are you smoking ?
First, the reward wouldn't be super duper awesome as you make it sound, since it would be like 20% improvements on the drop rates max.
Second, it's a reward for something, since you would have to actively work on your luck stat by doing everything right, so it's really not at all "by default" and not "extremely easy and unrewarding"
It would be a small reward for learning how to max your luck in specific occasions.
Actually, your comment is even more nonsensical than it looks at first glance, since it would change NOTHING to the positive aspects of current luck mechanic as it works RIGHT NOW and which you are defending.
I don't know, do you just like the average player to unknowingly suffer bad RNG without even knowing why, while only you and a select few who will know about and exploit this luck mechanic enjoy the benefits ? Because in the end so far it seems to be your only "argument" if we can call it that.
