I have about 30k xp now saved up. I need the tracks for the turret. I can get the upgraded 105mm without the tracks, and honestly, the 105mm looks better then the 120mm. (Higher standard ammo pen, faster reload, faster intra clip reload, better aim time and accuracy) The only thing the tier x cannon has going for it is the higher alpha damaged.
So, get the tracks then the turret then the 105 or 120? Or go straight for the better 105?
(Also, equipment suggestions?)
