1: (most important) Remove harsh duo penalty.
The game is advertised as multiplayer in the first sentence:
"An infinitely replayable multiplayer and single-player tower defense."
For me its either single player or smurfplayer. Or an " I don't care about my elo player." But not a multiplayer game.
I don't think thats the goal of the penalty? And the "problem" was a chinese duo who don't even play anymore.
2: Change leak gold. Not getting gold if your team mate leaks his opponent feels wrong. Example: You start nightmare on wave 1, your team mate leaks his fiesta opponent with a snail. And you still chilling with 4 workers on wave 2. This just feels bad and unfun. (maybe I'm biased but thats how it feels for me). This change just made the game giga predictable gold-wise and you never have a game where you can push that 1 worker extra out of nowhere.
3: Like suggested before: Change scrapper that the value generating units scrap for their base cost and not their actual in game value. This prevents scrapper from generating money.
4: Maybe a small robo nerf. This helps players to greed more early. Holding is just to important in the current state of the game.
5: Think about the mastermind "shown" at the start. I think that showing the masterminds will cause more unfun problems than it helps solving the problem.
Question for the devs regarding this. I see it as a QOL for kings guard. But besides stash I don't see any benefits of showing it.
It "solves" stash.
it "kills". Fiesta, cartell, castle and in some form miner.
I know this will be partly ingored and thats all fine, you can't pleasure everyone. But I have the feeling that more players share some of these suggestions.
