Highly support your request. The upgrade cost is way more than what the farm and Caravan produce. .Also, i feel percentage for the loot is high. Since couple days, i have an trying to save 150K for an upgrade and i was 1000 food short. I got raid 2 times in 12 mins and lost 49K. Just for comparison, in clash of clans i had 351K elixir and the loot available was just 32K. Even 8 hrs of peace treaty is not much of a use.
I think they should do something about it.
I've been playing since December and just moved to Enlightenment Age.
Firstly, the %loot able to be stolen from storages at around 22% and does not go down as you advance age. (although the loot cap increases) This allows active players to fill their storages faster.
Secondly the pathetic 4 hour shields and no bonus for winning. What this means is that an attacker can destroy your village up to 49%, take 22% of your storages, leave and then you won't get a shield, so another attacker can do the same all over again! And when someone does destroy your town centre, you get a small 4hour shield, or a 8hour shield if they destroy 50%. This means that there are more villages to attack 'on the market'
Unfortunately the game is not friendly to casual players who can't attack often or stay online for long periods of time. In any age, you have to attack multiple times in a row and stay online for you to upgrade or progress in this game. If you have more than a decent amount of loot, you will be attacked multiple times within 5 minutes of your phone 'sleeping'...therefore undoing any progress you made.
say you are 80% resource progress to your next upgrade after 3-5 attacks in a row, the last losing your entire army so you log off. Within 2 minutes of logging off you will be attacked twice (1st gets 49% and most of your loot, 2nd wipes you clean with 100%). Due to the loot % mechanics, that brings you back down to 50% of progress to your next upgrade as the % loot that can be stolen is so high
this will happen regardless whether your medal count is high or low. If it is low, weaker opponents will fail to get your loot and push your medal count back up high until someone trashes your base.
As farms and caravan upgrades are relatively cheap in comparison to defences etc, casual players upgrade them first to a high level...then give up the game, leading to more 'zombie villages' for other more active players to raid.
