tempest AOE as a buff
I find a lot of times that in a ZvP match up, tech switches from the zerg can be very devistating and a lot of times hard to keep up with. One unit that has been neglected a lot by protoss is the tempest. If you add AOE damage to the normal attack (of course not crazy like archon damage), wouldn't that help normalize the game a little better? SH wouldn't be as much of a pain and muta death ball switches wouldn't be as devistating. (it would give you just enough time to switch to pheonix). Also, since they are a slow unit they will be more of a defensive unit. They are as expensive to tech up to as colossus so it's not exactly the easy to get unit as well.
