"If paying for an advantage isn't worth it"
Therein lies your problem: there shouldn't be an advantage to paying in a game full stop.
You should pay if you want to have fun, not to purposefully get ahead of the competition.
If you paid for something, and then people got the better thing for free, perhaps you need to rethink your habits. Alternatively, you could welcome the fresh diversity into the previous paywall-only club that you "enjoyed".
I understand the frustration with the Revan-only meta: everyone does. However, that's a problem unto itself, not as a result of the f2p-ers: remember, only whales and the like could get him first time around proper. Being at the top insensitives people to spend money to continue to be at the top.
The fact that people who don't spend a single dime on this game can get into the top place is a sign of greatness on the part of the developers: they designed a functioning system, where everyone has a chance!
The cost of blurring the lines is simple: EA gets more money from frequent spenders than they do from people who shell out in one fell swoop. By nurturing a ground that encourages people to regularly spend money over time they get a higher profit. The truth is, whales and f2p-ers are much more similar than you think they are.
