[Khora farming become too grindy]

This game become too grindy when i decides want to get khora frame as the rotation c didnt drop khora systems while i had 6 main blue print. Could the rotation systems changes to less grindy? Perhaps the rng system can be tweaked a bit... when the subsequence parts didnt drop on this round makes the next round drop rate higher than the usual by percentage. So that there is set number run on this santuary onslaught less grindy. Its make me want to quit
