With Raids and Invasions, while they scale up, it isn’t insanely fast and takes time to go up and is never the same enemy teams to go fight over and over. I have never once seen either Zuul or Towers being paired up with transformation troops or anything too problematic unlike the crap Delves and Tower of Doom pull.
Delves are ESPECIALLY the worst. I couldn’t make it to the final reward as the game kept utterly cheating to prevent me from getting it (and even giving me a loss for a win. Screw you game!). The AI doesn’t even need to try as one little 3 match could be a skull cascade to them winning without needing to open their eyes.
The only way to combat delves is by upgrading the treasure hoard but since each one has their own separate hoard, it is stupidly impossible to do and since not everyone likes to be in pain suffering through the same 3 or 4 fights over and over again, the hoards should be together. I’d rather pay 1M a treasure to slowly upgrade a new faction’s quality over starting over again.
Then there is the rooms themselves. They are all designed to be as problematic and unfair to play against. Even if you have a team that can stop them, it still means nothing if you can’t get it active like Sylvanimora’s entangle which, spoiler alert, never happens when you need it. Bulette’s, Leviathan, TRANSFORMATION Troops, Goblin Throneroom, Dust Devils, Cockatrice, in fact, every troop at the high levels are all brutal and unfair.
I’ve had plenty of instances were I am about to win when all of a sudden, a simple three match for the enemy lets them get 3 skull matches in a row, killing my hero, killing two of my troops then spawning in 3 more enemies and then killing me off. Or the enemy is one hit from death and suddenly, the game drops skulls wherever I match in the perfect spots for the AI to match and kill me while also never triggering my troop’s resurrection chance (not stunned).
Tower of Doom is just as bad in this regard. While it ditches the stupid “Keep dead party members” rule, it has a mono color restriction which, unlike delve’s double color restriction, makes it more annoying and then there are the boon scrolls… why does it scale up with each level? The fact at +29 health requires 30 life scrolls for another +1 is absurd and unfair, especially for lower guilds.
The Doom’s also changing is a bad thing since you may need to adjust it accordingly lest you be stuck fighting a level 300 Clockwork Knight armoring itself up over and over after it killed your true damage dealer. Oh and the rewards from the last Tower of Doom show it isn’t a gem giver but rather a gem taker. Thanks(!)
In fact, now I think about it, the devs sure love to cripple newer players even more since, before the delve change, everyone could camp at 20 to get all the rewards with no problem and the people who wanted to move forward could and have the upper hand in those rewards. Now? No chance.
TLDR: Cut down on the uber powered troops.
