OK, let me try this one more time and I'm going to be as direct as possible.
With few, few excepts the ONLY influence NCNA staff has on this game is in regards to L2 Store items, promos, and events. If you want to see some semblance of balance its probably going to come from the L2 store (unfortunately). Having said that, the only realistic solutions are easily accessible (affordable) items which decrease damage. Another good change they could implement which wouldn't hurt their profits would be to make L2 store promo items have diminishing returns the higher you get them. For example, make it easy to obtain Greater Gems but harder to level them higher AND, make the difference between a lv1 and a lv10 relatively small.
