The point was to get to know what everything you have does and understand what can be achieved with what you already have. By understanding everything you have, knowing what it can do, you also will understand what it can't do and what, if anything you may want or need to improve your set-up. If you don't know what your current rig can do, how can you decide what you want/need to improve it. You also need to know what to look for, what it is you want, otherwise you will just be wasting time and money on buying things and not even understanding whether or not they are the right option for you.
A Helix is just one tool available to a guitarist and can be an entire rig for someone. It maybe the 'perfect' tool for a fly-gig for example but for another musician, its not what they want at all. The reason I mentioned Helix is because it can be a much cheaper and more versatile option than the rig you mentioned but whilst it maybe better for one, it may net be better for another.
Understanding what you already have will tell you where its strengths are, help you understand what it is you like and what you perhaps don't, what is missing or what elements are barely adequate and can be improved. If something is 'adequate', you need to know where its lacking to try and find something that is better.
For example, you have a Boss RC1 in that rig which is 'great' but if you want more than 1 channel - like having the bass line on one and rhythm on another, want to be able to store multiple loops you create, maybe even have a 'drum' pattern etc - its not going to give you that but until you understand what you actually need for your rig, its a very good looper and good be more than adequate for you. It may not need to be 'improved' because it does exactly what you want and need or maybe it does need to be replaced because you need more. That only comes from understanding what that pedal offers, using it enough to know whether its doing what you want and if not, what its missing so you can then go out and look for a looper that does offer what you want. The Headrush Looperboard could be 'superior' but a complete waste of money if its offering things you don't need or won't use.
The point I was making is that you really need to get to understand what your rig does for you. It could be the 'best' rig for you and do everything you want and/or need. Understand everything you can do with what you already have and only then can you understand what areas could be improved (if any) and what you may need your current rig can't offer. You may want Reverb but understanding what the different types of Reverb offer can help you decide which Reverb pedal to go for but without understanding, you don't know what reverb will give you the sound you want - which is the right one for you.
There is countless alternatives in every area in that signal path - as well as numerous different orders that will change the outcome of the sound. What maybe an 'improvement' from my perspective, what sound I want to achieve, could be very different from yours so any 'improvements' I would make, could be worse for you. This is why you really need to do the work yourself to learn and understand what each 'tool' in the chain offers. That's why you need to start by keeping it as simple as possible, get to learn all you can about your guitar and amp first then you will understand the interaction between these and their strengths/weaknesses. By knowing that, you can then make better choices as to what gear will build on the strengths and reduce or eliminate the weaknesses for you...
