Im Allhere:your strat is countered by wraiths btw. just want let you know.

Wraiths are extremely vulnerable to Cleansing Beam and fuel rod cannons.  Not to mention, they are little more than useless against an upgraded, flying PoR.  And the Elite Honor Guards have high survivability, especially when cloaked (which further adds a defensive bonus to incoming attacks).  Ghosts are fairly weak against them, but, as the experienced players have pointed out to me many times, it is always foolish to hit the left bumper and then press 'X', in combat.  Meaning, every unit is specialized, you can't expect to send them all into combat against the same type of unit, in most cases.

If a player masses Wraiths, then they have lost.  Send EGHs in first to absorb the damage, and then destory them with your PoR.

Summed up, I haven't lost to Wraiths yet.
