Lotta people seem to admire the use of pet play when in fact it favors the person who has nx.
No NXless person could EVER do the above.
Weekly rebirth is an NX advantage that you use.
Free NX surveys are available on the Nexon website, those who don't spend cash still have access to the cash shop.
I don't know any high level player without at least 2-3 pets. You have a Thoroughbred, why not also use it for some pet play?
IMO, paid rebirth is a much larger advantage than pets.
It allows a person to develop their character much much faster for much less work, at the cost of continual NX spending which many people can't afford. Pets are one-time investments that are much more feasible to the less wealthy.
