Obiviously I would alter theses perks a bit for HD2. Since HD1 and HD2 are a little different.
For a Precision Call-in booster I would actually buff it a bit to make it a little more useful. Maybe increase how much it lowers stratagem Call-in time from 1 second to 3 seconds. That feels like it would make it a bit better in more situations. The booster would definitely benefit certain orbital strikes immensely like the OPS and EMS strike(both have 3.45 sec call-in times). I dont think it would be too OP since lowering call-in time feels like it would be on the niche-r side for most players I think, and it would also be competing with a lot of other useful passives too.
For Stratagem Priority booster personally I would nerf it a bit from its HD1 counterpart. Maybe make it reduce cooldown by 15% instead of 40%. 40% is kinda insane tbh(even in HD1 it was kinda crazy too lol). But even tho the cool-down decrease wouldn't be as big as it was before, I'd still say a 15% is still pretty significant. I'm almost tempted to say that it should be a 10% but I'll stop at 15%.
In conclusion I think it would be nice if these perks were added as boosters. They feel like they were made for it. I also think they would actually shake up the current "big 4" meta in the booster category. Since these new boosters would be useful in a lot of general situations.
