There is a lot of confusion about this but few points are certain:
1. Devs didn't specify what are their goals with a complete overhaul of the entire game. This is where a lot of players get frustrated. We don't understand what are they trying to achieve. Some info would be very welcome.
2. Changing the combat affects the whole game - economy specifically. Making recruits, bowmen and cavalry pretty much obsolete on most of the adventures will send ripple effects throughout all players.
3. Making MA (the most expensive gen in the game) much, much less useful (testers say on most maps he under performs the vets) is a slap in the face to all of us who spend gems on buying 2nd one.
4. Time. We understand the devs spend most of their time on the game. But we players don't. FT adventures are already enough time consuming. With the new changes even the easy ones will take more time.
5. Time again. Using more Militia, Soldiers and Elite Soldiers will quickly run us dry since those units are not that fast to remake. It takes days to refill those.
What are the devs goals? Are we doing too many adventures, too fast according to them? Who is gonna do BK which will cost almost double amount of troops and time? All advance weapons are produced way too slow for us to make enough of them with the new changes. Do you know how long it takes to replace 200 Elite Soldiers? And how long it takes to make 200 D swords (granted you have all the materials for it). Removing weapons from loot drops? Not to mention the ocean of coal they will require. Where are we supposed to put all those coal makers? There is something seriously flawed here and I think it is not the changes but the goals of them. Unless you wanna lose half your subscribers...
You need to sit down and start thinking really hard about this. We asked for a slider to train more than 25 troops, we asked for pvp and we asked for more adventures. We DIDN'T ask for a complete overhaul of the entire game? And you say you listen to feedback? Wonder how many times a month...
