While I agree glimmer cap should be much higher (it's literally just a number, no inventory item or physical object your guardian carries), and mods should cost less, I have to say this is the first season I haven't gone broke in the first 2 weeks. And that's with also buying/completing like, 5 ada bounties on warlock and 6 on my titan.
Running the top tier glimmer mod for the ghost shell is huge if you want to avoid being broke.
