Perhaps mercs should not have "all" the upgrades an army created from a player base? It makes no sense that "mercs" have all the tech and upgrades a "Real" army has. It would be cool to see mercs with different upgrades. For an example..some merc squads can have the helmet upgrade..or others just have the shield upgrade. It gives a different look to armies and it would feel more "merc"ish. Having an uniform army made from your own base would give it more value too + another reason to create instead of simply buying.
