The more you have, the more troops you will have to heal and not train again.
Hospitals help you with your troops and makes it easier for you to rebuild defences after you are attacked. My rule is to have as many hospitals as I have barracks. It would be a great idea to move together with your alliance members – the proximity offers a ton of advantages and is the first thing needed to build a solid alliance (and keep you safe with their help). You will get a free item that allows you to teleport wherever you want to before your Stronghold reaches level 5. Use your teleport after joining an alliance
Also, this helps keep your alliance strong, which is the first step towards being the best.ĥ. Make sure to complete the alliance quests as soon as possible to make sure that you get the loyalty points and the gold.
