Thing is there need to be "radical" changes for people to give this game another try. And this change seems
radical to outsiders but isn't. That's why it works.
Simple quality of life improvements won't get people to think "
I didn't like this game before but now that they changed this and that I might give it another try".
Regarding the HC system I think the leveling process was by the far the main barrier to entry that put a lot of people off and still does. Without the XP mod you do have to spend maybe a couple of months (!!!) playing pretty regularly to even get a level 50 HC. Then because you're a noob you didn't realise you were supposed to use an Asian city and well fuck this game.
Despite being such a simple and easy change it has huge, and RADICAL repercussions.
The vast majority of the hate directed at the HC system from other communities I've looked at is targeted towards the leveling system.
131 decks doesn't add anything for me and personally I enjoy looking at the enemy deck and seeing what military shipments they have left, what capabilities do they have right now? etc and planning a little around that in the game.
I could get behind making a few more cards viable but I like that you need a deck.
Edit: Ah eagle beat me to it, zzzz.
