It's not the monsters' levels that are the problem

At least let me train on monsters 5 levels higher than me without missing so much with decent accuracy, Nexon!

I keep hearing that, phrased in so many different ways.
So much frustration.
But, is the level really the problem?
If Nexon were to say, "OK, we fixed the accuracy formula, it now starts penalizing only at 10 levels above your own.
BTW, we also increased all mob levels by 10."
Would that make you happier?
You'll be able to train on monsters 10 levels above your own, or even 15 levels if you are willing to tolerate a 25% miss rate.

But you'll still be frustrated, and you know why? Because the monsters are wimps!
Most players are able to 1-2 hit anything the accuracy formula allows them to train on. It feels like you're forever training on snails. And that won't change with the above scenario.

I think that if Nexon were to leave the accuracy formula and mob levels alone, but increase all mob HP and EXP five-fold, player satisfaction would be much higher, with no real change to the game.
Leveling speed might increase somewhat, because you'll be spending less time chasing after enemies and more time killing, and also because the really well-equipped could kill in 2-3 hits as opposed to the average player's 5-10, but I think it won't be that significant.
What will be significant is the feeling that you are getting a challenge worthy of your pro-ness, something that actually takes all your power, applied several times, to take down. And gives a worthy reward. (Something like the idea behind LHC, if I understand it correctly). You won't feel the need to train on mobs 5 levels higher, when mobs your own level are tough enough and give good exp.

Of course if they do both, increase HP and EXP *and* increase levels while raising the accuracy penalty threshold, that would make people even happier.

What do you think?
