Strategies:- Wraiths are fairly good phasic poccers because of their high weight and space as well as base armor. Its base armor is fairly higher then the rest and with its space and weight capacity, it is able to last for quite a while on the POC. However, the Wraith is mostly a GA type unit as most of its weapons are GA.
GA:- Wraiths, though slow and clumsy, make good stationary GA units. With their high armor, they can slowly plow the field in search of out of energy units or other slow air units like Condors and Rocs. But the GA status comes with a price as they are vulnerable to land and arb fire. Wraiths also make good Roc stoppers as their speed are almost the same as the Wraith. Having a couple of Wraiths standing right below the Roc and a few more further away from the Roc, you can let the ones below shoot it first, then let the ones which are further follow it and you can repeat the process.
Phasic Poccer:- Wraiths with the role of phasic poccing don't need any weapons to defend itself as with the excellent armor and HP, who needs to defend?? With a combo of 120 Edu and at least 80 MA, you are able to fit in ALOT of armor and good biodrives. This gives you very high HP and armor. A typical level 60 Wraith which is dedicated to poccing would be followed by a phasic roc and would have at least 8000HP with 102 armor. This would allow them to be phase slowly, one at a time onto the POC.
