The raid is all about teamwork.

You know how the borg adapt to attacks? Why not have a shielded enemy that does something similar? It may have a solar shield, but after it's attacked with solar damage it adapts and puts up a different color shield, requiring someone else on your team to take it down.

Have a few of these at once, and now your team is tasked with rotating and attacking the enemies in the best way possible.

Moar raids plz

* - I guess resistance was futile :3
