Liquid Defiance EGO scaling maybe but I am at threat 2 normally, just upgraded from threat 1. I play it casually over last year whenever I want to shoot something, but if I get trapped in a quest with threat 10 it is always a tough fight that I cannot survive, and better off escaping and going back when they leave the area. Enemies are more numerous and of the harder variety and I cannot compete as a casual player. But you should go back and play v2 of the game, when it went f2p they made the p2p boost seriously powerful as an incentive to buy, it did not used to be that way as now my EGO level is rapidly increasing compared to before despite still just playing it casually (I do a mission once or twice a week and just finished the story). I don't even need to do mission just login everyday and I will get bonus daily/weekly goodies in the mail, including arkforge needed to upgrade weapons and now I am purple and orange everywhere instead of just a few blues. The orginal p2p version before the MMO grinders complained and got EGO limits raised was a much better game. I know I suck as a casual player and should not be hitting leaderboards just because I am a paid player, but the certainly are lowering f2p player ranks because they want them to pay to win.
I played Morrowind and Skyrim, I actually prefer Skyrims scaling better because you are more free to make a different path thru the game, which is important for alt play. If the game has areas that says you cannot go there because it is hard then that puts you on a predefined path - and I am hating that part of ESO. But that does not mean make it all easy or all hard, mudcrabs should stay easy and daedra should stay hard. This is something ESO got wrong as they have zones where mudcrabs are hard and daedra are easy. Its like playing D&D where the kobolds are as tough as dragons, and dragons are the easymob level one, it makes no sense!
It is fun to replay a dungeon at a different level than your other character did or even the same character going back. In skyrim I use a bandit mod that shows the tougher bandits taking over after you clear out the easy bandits (made the mistake of using a bandit camp as my own), helps with the immersion of why scaling happens.
Wurm Online has different levels of the same mob mixed together such as age, hunger, disease and traits but they are not autoscaled to you nor based on zones, so it makes realistic sense for an open world and you learn to avoid the hard ones and go after the easy. And rats are always easy and crocs are always killer. It keeps the incentive to upgrade gear and skills, while not mob blocking you from going anywhere though you might have to sneak past some mobs. ESO would be much better if they had taken that approach, they even downsized the Skyrim bear and sabre cats to reinforce that they are just trash mobs! Pathea wanted to do that way but already had to cut mob size options for performance, so unlikely we will see that here.
