yes, keep in mine this. When activate and if you are high or low grinder it does require proper gold administration to level up parts, enhance base etc.
My recommendation is this as basic
1- Only improve base till you can get the 4 gold mines. Do not go further for the 4 factory till later.
2- Factories do not enhance them beyond L2 because in L2 give "RARE" option like silver box acc. That it is good enough
if need to craft few parts under control.
3- Do not craft just to craft. Keep saving gold as much you can and use in the beginning the mix boxes farmed.
4- When have some gold stash enhance gold mines at the low levels and till L8 is affordable then spike on prices and need to control for level one factory at the time 1 level up to manage gold for other things.
5- If you farm heavy even so it is not easy to enhance base. If you grind little will take forever but can do it.
6- If you follow this basic you will level up mechs, make myths, and start to get some gold from mines.
7- Depending where at you in the acc progress in the arena shop it might be ok to enhance some go faster gold in the low level side but before that enhance your mechs health, shields, fuel etc. Just balance.
