What to do with units? Never been able to save them but times are changing
After watching brian grants video of how to farm revives I have started doing the solo events every day to the 4th milestone. I have seen a steady uprising in my units and in 2 weeks I've gone from 750 to 1850 untis. I also have the monthly subscription card that gives 600 units/month (refreshed it in that 2 week period from above).
For the first time in my 4/5 years playing this game I've been able to save up some units and feel like I can keep on doing so. Normally I start spending on cavs when I'm around 2000 units when I'm drinking with the boys (for the couple of times I've been able to save up that many lol).
So now I don't know how to get the best value, let me know your thoughts below. For context I'm already thronebreaker.
