Do you feel Nexon exploits it's playerbase?

The silly part of the argument with MTS is that someone, somewhere, has to pay money for NX. It might not be you, but someone is. The entire game revolves around spending money on NX. Even if you can merchant well, and end up spending no money yourself, someone else is essentially flipping the bill for you. There's absolutely no way around it. The entire Cash Shop and MTS systems revolve around exploiting players for every dime they have. Jackpots, expiring items, and lucky draws on potential that are practically a necessity result in NX being a must. If NX is a must, even if you use MTS to avoid spending money, means that SOMEONE is paying money to Nexon. Even if the majority of the player base is expert merchants, and can avoid the billing page on Nexon's site completely, that just means that the majority of people who pay for NX, pay for a ton of NX. Someone is paying for the NX, it's the simple truth.

The only question that remains is if Nexon is exploiting the players with the system in general. The answer is simple, yes. The rest of this thread has made that abundantly clear.
