Was just discussing this in gossip, so I wondered if the developers were considering this as well.
The way leveling stats in this game works is by speaking to a trainer and trading practice points and money for higher levels. However, raising skills requires no visits to trainers. If striving for realism, these methods of leveling clash and don't make much sense.
In my opinion, it would be more realistic to have players level stats without trainer visits and level skills by visiting a trainer every 10-20 levels or so.
The other issue, which a lot of noobs face, is that stat trainers are difficult to find. You'd think that they would advertise their profession, given they take money to give players levels. Once again, advertising, "I'll help you build agility," doesn't make much sense, so switching the methods of leveling for skills and stats would make more sense here. Imagine seeing a poster that says, "Looking for a sword trainer? ___ will teach you in the Arena!"
The real purpose for this post is to know whether the developers plan to change this inconsistency, but I invite discussion from regular players. I really want to see this change, possibly to something better than what I suggested above.
