i kinda agree with Xtopher idea..
maybe we can have lvling npc for example; 10 lvl : 10m-50m or any value.. max lvl : 800m just an example.. since some people gets hard time in leeching and lvling specially to the new palyers, where they need to pay 5 dqs for it or soome giving it for free..
i also suggest a forsaken bank, to store our gears for few hours or days, the procedure is by paying with zenny (dpending how long we want to store the gears) to the npc for few million of zenny and we choose how many hours or day and insert the items we want to store, after that the npc giving a 4 number pin. Then when we want to take it back just go to the bank and enter the pin.. If the person wants to take it earlier b4 the times end the bank require some amount of zenny, maybe it's kind of complicated but i just put what i have in mind..
and thats all
