I recently bought the sub, so my knowledge of the game is, well it's almost zero

One thing I want to do is try each basic class (7 of them), and take them all to 10. This will give me a good feel for each class and help me understand each one a little better.

Now my question is the following... if you had plans to take the first basic jobs to 10 maybe 20, then call the druid your main, what would be the TP points you would invest into?

Thanks.
