Dragoons are already overshadowing too much of Artanis tech tree. Mass dragoons with some sacrificial spin-lots to tank works against everything. Yeah high archon / spin-lots will be better against swarmy comps but spin-lot / dragoon still works. Immortals are fine, especially against ground mech but it’s not like dragoons who also have armored bonus damage, longer range, and can shoot air can’t do the job.
I’m kind of glad P1 promotes the rest of Artanis tech tree. Personally I think the P1 unit costs penalty is too steep unless your going for the high templar build, in which case it is just right. Would like to see the penalty applied to gateway units only (again P1 high templar / spin-lots are really strong even with increased costs) , or perhaps have the cost increase only be like 10% for robotics and stargate units with P1.
P1 has the potential to make Phoenix, Immortals, Tempest, and Reaver builds very good (yes Immortals and Tempest have some utility outside of P1 but are arguably over shined by mass dragoons) . With the cost penalty I find myself forced to go zealot / high templar and storm everything with P1, even though P1 Phoenix are kind of good. I think having less steep Robotics and Stargate cost penalty can put other P1 builds on par with zealot / high templar.
