There are two sides of this that you write about.
1. Traktor is a powerfull software that has a lot of features.
The backside of that is that it takes a little time to learn if you shall be able to
use the full power of it. But if you do IMO it is the best DJ prog out there.
If you give it some time and read the manual and even buy a copy of the Traktor Bible
then I do think that you will like it….
2. If you like Serato Intro and it works for you and you do not miss any funktion
Then why not stick with that and sell you copy of T2 or even try to return it and get your money back?
