Is RJT worth sinking gear into?

I'll first say that I did not spend a dime on anything to acquire and max out RJT 10 minutes after release. I bought the vets shards in the shops when they first arrived to 4*. Started hoarding crystals, omegas, zetas, gear, and credits a week before double drops...finished vets this past Monday...by last night, had 8 carbs, 6 guns, and 4 cuffs, enough crystals to buy the 2 pieces of gold gear to get her to g12 and throw on 2 zetas. How did I do this? I didn't use any of those items on any other toon in anticipation of RJT. This game is about resource management. That has been said many times before by several different people who reside at the top of the arenas. The people who say it is not possible to obtain RJT and max her out immediately have to admit to themselves at some point that until they completely embrace the fact that the most important skill in the game is managing your resources, they will assume (incorrectly) that the only way to compete is spend money.
