Gold and ISO-8

I'm a player who has a 7 year old account, I only play alliance war and alliance quest with occasional monthly or side quest when the rewards warrant my time. I never have any gold or any iso to rank up champions. I just pulled Peni Parker have everything to take her to rank 5/65 but I have no gold and no ISO. This has been going on way too long, it makes me want to quit the game.

If you aren't doing the game content to get shards/crystals (duping champs really is the best ISO source) then I don't really know what to tell you.
Iso is easy to get as of now
It would be no different if I said I mostly only grind arena and I never have enough catalysts to rank up my champions. The arena for the most part doesn’t have higher tier catalysts, so of course anyone limiting themselves to just that mode is going to suffer a shortage of those.
The various resources and currencies are distributed throughout the game. You can choose to play whichever ones you want, but you’ll be limited in what rewards you can get depending on which ones you pick, and how much effort you put into them.
