So I was looking at a particular piece of artwork on the site, and it gave me an idea for a unique replacement for the Shield Battery (which, due to the new Protoss shield regeneration mechanic seems obsolete).
The artwork in question can be found via this link

If you look at the concept, it appears that the possible building (or unit) in question has no apparant firing mechanism. Therefore, this is my suggestion.
Shield Generator: Recognizing the need to protect Protoss settlements has risen in priority due to the loss of Aiur, the Protoss have made several defensive modifications to their powerful shielding systems. Among these included a drastic change to the existing Shield Battery, using its energies to project a defensive shield within an area as opposed to rejuvenating the shields of Protoss military forces.
Explanation: The Shield Generator would project a protective field within a certain radius around the Generator that would act as a secondary shield for Protoss units and structures in its AoE. The projected shield would be powered by the Shield Generator's energy bar (250 energy) and would not drain energy until the shield came under fire, however will not gain energy until deactivated.
NOTE: When I say projected, I do NOT mean a literal projected shield (as in the Bubble Shield). The only graphics I had imagined being associated with the Shield Generator was an incative/active model for the Shield Generator (basically a model for when the ability is on and one for when the ability is off) and then a colored circle that appears when the player clicks on the Shield Generator (that is only visible to the player that built it, just like a Pylon) that represents the area that is protected by an active Shield Generator.
The shield would not benefit from shield upgrades, and the amount of energy drained would be equal to the damage caused by the attack.
Overlapping shields would share the damage, causing the energy drained to be less (for example, if a marine attacked one active shield, 6 energy would be drained from the Shield Generator. However, if the same marine attacked a unit under the protection of 2 Shield Generators, each one would only lose 3 energy) The Generator will lose AT LEAST 1 energy, regardless of the number of overlaps.
Finally, damage directed to units under the effects of the Shield Generator will be absorbed completely by the Generator until it has exhausted its energy.
Reason: Because the Shield Battery is no longer going to be in the game, I thought it would be nice to have a replacement for this popular defensive Protoss structure. As is, it is only a viable option for increasing Protoss base survivability and cannot be used in an offensive fashion.
玩家看到这幅图，然后有了联想。

护盾发生器会在作用范围内产生一个力场，为其中的单位吸收伤害。你可以选择打开发生器以产生防护力场，此时所有作用范围内的部队和建筑所受到的伤害均会被吸收，转为消耗护盾发生器的能量，但激活并维持防护力场不消耗能量；在关闭防护力场之前，护盾发生器的能量不会自动回复。
你不会看到身上有防护力场的单位带着一个类似真言术·盾的大泡泡满街跑；你所唯一能看到的动画就是护盾发生器处于激活/关闭状态。玩家可以点击发生器来查看作用范围，这点上和神族水晶塔类似。
同时处在多个防护力场覆盖范围中的单位，所受到的伤害由这些发生器均摊能量消耗；无论单位被多少力场覆盖，每次吸收伤害，消耗至少1能量。
开发团队的Cavez同学：
Noted. =)
收到。
看来开发团队会考虑这个意见，我们有可能见到这个建筑...以上。
