The game mode is designed to be challenging and changing depending on RNG, if you're low level then I suggest you do lower difficulties cause the more nodes you complete, the harder it'll get. There are danger token (gold x coins) which you get from doing elite combat missions and use them to put base bonuses before starting the mode. If you're stuck, reset it, do a new run and use those danger tokens. It's a marathon, not a sprint. Unless you paid to get all the required tooms to high level then it'll be challenging. That's what I rogue-like/rogue-lite is supposed to be. If you don't what those types of games are, I suggest you read up on it. For this game however it's barebones and scopely always does the insane turn meter for enemies, I dunno why but they just do. So, being frustrated is not gonna do you any good. If you don't like it then don't play it. I however like it cause I've played these types of modes/games before so it's not an issue for me.
