What is the advantage of using enhancers like pylarch/elixirs/general equipments etc. if the basis of making the banks full is resources.

Is it better not to use those enhancers while playing PP?

it only shows that they are just making a delay in making our banks full.

What is your thoughts about this?

They make your Units stronger. Which means that certain Rss value will be gathered from more Positions. It's a good boost when you're defeating high-level Positions that require losing a huge army. You can minimize your losses per Position then :)
