Is 1-20 Too fast?

[Cairdeas]

The super fast 1-20 ranking has only been put into place so new people don't quit before they get their first class mission. SE expects people to get hooked on the mission stuff so they'll put up with the more tougher grinding just to get their next crackfix, I mean... mission

I understand that. But compared to the rest of the game its too fast. Either they need to rebalance everything 20-50 or they need to tweak 1-50 total so it balances out.
