This comes up all the time.
You get a level 50 PVP character - Temporal Warrior - when you make a character. That's for PVP game balance.
Things against auto-50s for PVE.
1) If you really want to auto-50, just door sit in the AE for an hour to 2.
2) The renaming policy (if it ever goes into effect) means all those auto-level 50's would never have to log in again in order to keep their name. Meanwhile, lower level characters that aren't 50 - regardless of how long they have been played - have to be logged in every set number of days or their name will be free to be grabbed until they log back in.
3) Why do you need so many level 50?
4) The actual game is level 1-49. Level 50 is only the end-game. Content stuck on the end of the actual game. There is much more game content than there is end-game content.
5) Other level 50's don't like have an unslotted level 50 on a team .... let alone a level 50 that has no idea how to play their character.
6) This isn't WoW or Everquest - there are constantly people leveling up characters and, if you can't find a team, people will join you if you recruit for whatever content you want to play most of the time (this of course is server/time of day/population level dependant)
This is never going to happen.
This pushes it way over the shaky ground to troublesville.
It is selling something.
Homecoming doesn't sell anything and for good reason.
Look like you found your bliss.
Have fun on the Beta servers .... but ... you should know that periodically all the characters on the Beta servers are deleted.
