Perhaps the TA in AH serves the same function as the newbie arena in AW with veterans and trainers helping newbies and the lack of damage and scoring limiting the baby seal clubbing.
No offense but it sounds to me like someone is concerned that their job is being undermined.
There is no comparison between the AW newbie arena and the TA here. Its apples and oranges
Other comparisons would be that in AW the newbie arena was actually used pretty extensively. Here. Not so much. Of those that come to AH, try it then leave. How many seek out trainers or use the TA before they leave? I'd be willing to bet its but a fraction of those that come and dont stay. You would know better then I but I'd be wiling to bet that the TA is used mostly by folks who have been here past the free two weeks.
People by nature dont want to be "trained" right off the bat, And they dont want No damage or no score. They want to jump right in and play, set planes on fire and watch things go boom. Especially if they are only getting it free for two weeks. Now Im not saying that two weeks free needs to be changed. Nor is it a complaint about it. But they arent going to in their mind "waste" time from their two weeks to be trained. They want to jump in and just play against other people unencumbered by a trainer.
Again. A Newbie arena would allow them to play in an MA type setting where they really can shoot and blow up other people against those people who are close to their skill level because everyone there is a newbie. And without being little more then a baby seal because Vets, cept for trainers would not be allowed in.
By the time a newbie gets to the level where his opponents become baby seals. His score should be reflective of that. And at which point he would be forced to migrate to either the TA. Where you would reside for further and more structured and advanced training. Or to the MA.
To prevent MA regulars from heading to the newbie arena. Allowance into the Newbie arena could be determined by how much time one has spent in the MA.
Say, 3 weeks. Once you have spent 3 weeks in the MA you would no longer be allowed into the Newbie Arena and instead would be referred to by way of pop up suggestion to the TA.
Example of such a message
"You have exceeded your time allotment in the main arena for admission to the Newb arena.
For further and more advanced training. which will result in a better gaming experience
It is strongly suggested you try the TA where trainers are available to help you"
