I'm a returning payer after quitting the game about two years ago and have some catching up to do. Planning to buy a hero from the gear store this month. Mainly I need to farm medals (HZ 90 would be ideal) and of course upgrade parts from faction bases, all of which are still pretty much out of reach for me at the moment. I did purchase a jug but it will take some time to get it upgraded to the point where it's useful.
I have plenty of workshopped libs, ZK's, a couple of envoys, Herald, a few Cyclopes, Phalanxes, technicals and caretakers, all undergoing upgrades averaging about level 6 or 7. This takes time but I constantly have as many upgrades running as the game allows. Libs and ZK's are level 11 or 12.
Which hero is my best bet to purchase first for my needs, Polly or Santiago?
