Every single thing for a character is technically available from the first moment of play. You collect points and experience and cash them in as you fit, โskipping overโ whatever you want.
The best abilities would obviously be the most expensive, but theoretically if you wanted you could play a bare bones base character and just grind for the ultimate ability straight away. This would take a long time, but less time than it would take you to get it via a skill tree. Trade-off of course being that you still now have nothing else.
