I wil say that the gen 1 slides were clumsy and early units could be broken by forcing them in backwards. It always felt like the part which was the least well designed. I like the new magnetic interface but I agree it's kind of an odd thing to have a minor quality of life update be the top line.
But also, don't be afraid to just read this stuff online. The game is so big it gets tedious if you don't have a huge amount of time to devote to it. That can really kill motivation to keep going.
This is honestly the biggest disappointment in the third game and is due to the console focus. The second game has much deeper combat because kb&m really opens up ability to get creative with complex magic, potion and swordplay combos.
As the movie industry discovered, it's a dice roll in terms of pissing off the censors. Hard to invest millions when something as stupid as a map can get your game banned.
