Even if Harvs would be added they would have the same HP value as either SU or CU just with the added Interc BUT those would need to be adjusted so that they have a very low Cryo Value cus otherwise there would be no reason to even kill a Harv and simply let it reset to have 10 Interc again what in return would break the respawn time of Siri units what is ~8-10 mins from my last testings.
I can totaly live with the system as it is now cus we have already plenty of option to farm in Siri with DR Tech what makes a lot of hunting in Siri trivial while still giving the option to hunt in TC as well.
