I have been thinking and the more I think about it the more I am going have to say that I think this fear is unfounded; the apex of player ability; is to have the knowledge; and skill in this game to be able to run and run effectively at isk costs and fitting; trading off proper modules for gains and advantages and this scenario would actually justify the use of CPU and PG modules as they're no longer not paying their slot consumption weight barely but being able to enjoy it further out for higher grade modules elsewhere. A second or third fitting module would simply make it a std slot layout with full adv-proto mix.

Even if a highly skilled veteran where to make an unusual glass house fit to get a performance not normally seen at that 'tier' a lesser skilled player can attempt to mimic the setup using weaker gear but having access to the same slots can empower the player to achieve semi-relatable performance instead of a gulf of impossibility.

There are ways to balance this fear out though; you can simply adjust the fitting modules; make officers/experimental harder to fit so that only prototype suits would fancy fitting them; adding additional module fitting skills to modules that do not currently enjoy them and much more.

a STD core plus 4 pg upgrades and 4 cpu upgrades is much higher than a proto core, if I use std and pro dropsuit values and 4 and 8 slots comparatively
