oh great I can really see your point maths & fun really go hand in hand.
People should have never reduced this game to 'simple' math. Its not how it should work.
Actually, that's almost exactly how it works.
This game (and, to be fair, pretty much any RPG in the last 20 years, either MMO or otherwise) is entirely math-based.
Numbers govern EVERYthing you do in L2, from how much damage you deal, to how long you live in combat, to what grade of weapons & armor you can use, to what you can buy and carry, to how often creatures drop certain items, to how quickly or frequently you can cast spells and craft gear.
Every single aspect of this game boils down to "simple math"... some of which, in actual fact, isn't all that simple sometimes.
It just so happens that the most prominent parts of all this math are the XP bar and your adena total, because those numbers are what ultimately dictate the advancement of all your other numbers.
So naturally, the math of increasing those as frequently & quickly as possible is what a lot of people will get hung up on.
To say this game should not be reduced to mathematics is a total misstatement. This game IS mathematics. Having your numbers be bigger than the other guy's numbers - either another player or a computer-controlled mob - is the ultimate goal of playing this game.
The only difference lies in the fact that some people choose to enjoy the journey of working toward that goal, while others enjoy accomplishing the goal itself.
I do see your point about "experiencing the game", and I actually do agree. But I think it needs to be pointed out that, given these facts, getting so upset at people who play by the numbers is sort of a ridiculous position to take.
