I'm interested in finding out how everybody feels towards upgrading. Sure it makes your units a hell of a lot more powerful but is it truly worth it? When you're a lower level and you're using scavengers and infantry as your main unit type, its a no brainer to get the upgrades especially as how cheap they are... But what about when you're much higher.. and you're using jet troopers.. tanks or even helicopters? Is it really worth say a 14000 resource investment just to give your unit a +1 movement? Or would you rather just put that hefty amount of resources towards the next unit unlock? To me upgrades are important but I can be skeptical towards some units and the fee they charge... Pretty much my scavengers.. infantry and APC are fully upgraded... but when I unlock jet troopers next I'm unsure if I'll be putting upgrades on them... How do you guys feel?
