In Evony it is entirely possible to run a 100% tax rate. This means your population will constantly dwindle because your loyalty will be going down. As your loyalty goes down so does your population and eventually your town will revolt.
However you can use comforting to increase your loyalty or increase your population. Since you can perform comforting every 15 minutes you can maintain your population level/loyalty. However if you forget to use comforting or if you are going to be offline for awhile (maybe to go to work, school, your job, or just to take a break from Evony) then you stand a chance that you’ll log back in to find your army deserted you and your towns people are revolting.
So why would you want to run a 100% tax rate? This tax rate allows you to maximize the revenue you make from your towns people. The gold can help you hire high level heroes, buy resources, or research in the academy. Since things like “construction” or “archery” are key research items the sooner you can advance those skills the better. Some players like to run the risk and run a high tax level at first. These are players that can be online for 4 to 8 to 12 hours at a time. They can constantly use comforting every 15 minutes to raise their loyalty/population.
Just keep in mind if you try this method to be sure to reset your tax rate to 50% or 30% when you log off. Otherwise you may login to find you have very little if any loyalty and your townspeople will be trying to start a revolt against you. I had that happen and it isn’t pretty 😉
