I would suggest some method in Sirius Singularity to guarantee a specific BP drop. Like, if there was a special "Oracle" mission on R1 planets, and when a clan completes that mission for the first time, the clan then unlocks a "Fortold Future" mission on an R5 planet, which gives access to a specific Ancient BP tech that would allow clans to bypass the potential 4+ month cooldown on a specific print. The elevator pitch is that a clan can achieve any R5 dropping bp in under 7 days, no matter the time of year, but it's not so easy to get bps that a clan would ignore the 13 dropping bps every 1-2 days on new planets.
Some BPs are very hard to get. Sol sniper tech and draconis defender tech are difficult, but warranted to get, requiring over 10 goldbps from specific sometimes low-count enemies, like DS heads and minelayers. What's unwarranted was making the grind even harder for new players: to equip any of this tech, you need to grind specific sometimes low-count enemies from lower systems like Mizar's one mender that drops repair turret and Sol's R60 free roaming rezurector to equip them. The rare bp decryption system would make more sense for lower systems to require all the blue bps of that tech in that system required instead of all rares of that tech from lower systems required. And to step away from lower system rares, TC blue bps can sometimes be ridiculous to get. "Kill at least 11 ds heads for blue speed actuator". "This one mender on the whole map drops 12 deflection droid bps and 10 thermoblast bps." The mender requirement means that a single blue bp requires by my estimate at least 10 hours of waiting for a respawn on a single mender, which can be above the average rare bp grind. It looks like the mender drops drops deflection droid and thermoblast because they ran out of units to drop bps from and shoehorned them in somewhere. A quick fix would be make the mender lander drones drop bps, any unit from the ds drops the bps, or fewer bps required to unlock the print, with the elevator pitch being an attempt to equalize theoretical new player time investment to blue bp acquisition.
I like the idea to remove ancient balanced from lower systems. I don't like that all systems just become purple blasters, the rare blasters are cool. At least rare blaster is somewhat competitive with balanced, but 5% damage buff is actually a crazy number for pvp effectiveness.(which people who swap drones all the time should know- 7.5% cdr is INSANE, 10% damage/hp from old drone is INSANE, 15% flight speed is INSANE, +10-15% range is INSANE, no wonder people are talking about swapping drones mid fight.)
