What I want to suggest is more a discussion than an actual suggestion to the game. I have a feeling this has already been discussed in the past, but I couldn't find any threads about it - probably because the keywords are too vague. If that's the case please supply a link to the original and do whatever it's done with duplicates if this one adds nothing to the subject. So...
Why don't players learn from experience, as in most games, and as IRL? I know HnH isn't most games nor real life, but it doesn't make much sense to me that, for example, one does a lot of farming but doesn't gain any "Farming skill" from it, or that one uses ranged weapons a lot but doesn't get any better at aiming, and that at the same time a more advanced player can create an alternative character and make it highly specialized in, say, melee fighting, in just a few days and without ever actually having a fight. Or even a troll-killing alt in a few minutes, like https://www.youtube.com/watch?v=Stg1B96WRd0 (if that still works). I mean, you're not rewarding the effort put into a task.
I'm not suggesting to get rid of curiosities, etc, just to diminish it's role on LP earning and conciliate it with a "learn from experience" system - which could also have it's multipliers. Honestly I haven't played enough HnH to know how the LP system works out on the advanced player, but from what I see on videos and images - as mentioned above - it gets relatively easy to acquire LPs after some time and thus it's easy to have a character absurdly specialized in a task it doesn't even do that often, while the not-so-advanced player, which might do the same task even more often, isn't really rewarded for doing it.
As I said I haven't been too long on HnH. So, what are the negative implications of such system, if any? Isn't it a thing to consider?
