Bring balance to gear 13 pieces sources

As I relic more characters, I've found there to be a notable in-balance in energy sources for gear. Using Han Solo as an example:

240 pieces of gear are exclusively gotten from normal energy (this includes 100 kyro)
430 are exclusively fleet energy. 

There are 100 pieces that can be gotten from both energy types, but 50 of them are from a hard fleet and then you are done for the day (no other fleet battles available). 

Why does this in-balance exist? can it not be fixed? it's causing a notable bottleneck because I can't use both energies to get to relic.
