rop Pod: 100/200. Can be called anywhere. Instantly re-enforces units in radius. Provides minimal damage and knockback at target area (does it still do this?). Provides no new units.
Call Da Boyz: 250/200. Can be called only in immediate vicinity of leader. Instantly re-enforces units in radius. Provides a buff to units in radius. Provides no new units.
Warrior Vanguard: 300/150. Can be called anywhere. Provides re-enforcement radius. Provides a new unit of Warriors.
These seem very balanced to me. The Warrior vanguard provides what amounts to a deep strike of warriors anywhere on the field and a re-enforcement radius, which is very valuable to swarmy races. It provides no other buffs or benefits like the others do, and always exactly performs for cost instead of occasionally being very profitable, but in exchange it has a 25% lower red cost than the other two.
That is to say, Drop Pod and Call Da Boyz are basically like trading red for req. The Brood trades less red, but instead of getting a req discount, you pay full costs but have the additional benefit of a lingering re-enforcement zone.
I mean, can you really call that a "no brainer" balance issue?
