Krakia?

none of the things you've brought up compare to the changes big bang will bring. leaving areas like cwk in tact will cost them far too much for them to ignore it. as is obvious from their website and it being the hottest selling item, 2x cards are their main source of income. if they make it easy to train (post bb with current exp rates, wr would be good well into your 140s) they would end up losing thousands of dollars worth of 2x cards per month. nexon america isn't in the habit of wasting opportunities for money.

All that would need to be done is exp changes on mobs. Even then, they dont need to really change anything.
