There's the rub. You don't appear to be reading much of anything.
1. You don't HAVE to have a high BSI or high LSI. Build according to what best suits your playing style. Just be aware that some things are just going to be out of your reach UNLESS you are prepared to spend money on it.
2. You want a Warbanner. That's cool, most people seem to want them. So folks told you how you could go about getting one or more.
Just because YOU don't want to do those things does not mean the Dev's need to make a special one just for you.
