How are you supposed to engage Carrier/Tempest/High Templar now?

So my ladder experience today has been 8 Protoss players in a row. All of them went straight to high templar then straight to skytoss. Tempests outrange everything, if I try to move forwards to attack a base they snipe half of my lurkers before I even burrow and then storm kills the rest. Same thing with my Vipers. They're dead before they even get to cast an ability on their army. Then if I actually manage to engage this army sitting behind 10 cannons they just blanket storm everything, including their own army and win the engagement. No clue how anyone thought this new storm was a good idea.
