What do you mean by “scroll well”?   Are you saying that you cannot cut shapes/curves very well?
A bandsaw has two challenges: to cut curves and to cut straight lines without wandering.  It is nearly impossible for the same blade to do both very well. 
If you want to scroll cut, you want a very narrow, thin blade.   However this blade is going to be terrible for resawing (cutting scales from a block, for example) and they are a gigantic pain to get the tracking right.
A blade this is 1/2” or wider will track straighter but isn’t going to do tight scroll work. 
As a blade dulls it is going to want to pull to one side all the time when you cut.
I have a small 9” Grizzly bandsaw.  It’s great for what it is, but there’s a reason companies make bigger, better saws.   We have to be realistic about our expectations on these little mini-saws.
