I'm not sure fascination would the correct term. Preferred, maybe?This. I absolutely love drafting MTG and I think arena is just complete garbage. I don't care how good or bad you are at it, I don't understand the fascination.
The card variety is much higher while the game variety lower, both of which I like. It becomes (too?)easy to tell what the opponent is going to play on certain turns once you figure out what deck they are playing, which can be as easy as identifying their hero because they only have one good ladder deck. It gets boring playing against the same decks and cards over and over. I'll admit, though, arena is not immune to this as 3 heroes dominate probably 50%+ of the matchup.
Arena is dominated by tempo game style, which I like very much. Your opponents plays threats and you, most of the time, have a chance to answer them. Non-interactive threats, which comprise a non-insignificant portion of ladder, are very much not fun to play against. FoN + SR and freeze mages are probably the prime example of this but I'll include things like brawl and light bomb. Sure, you have a choice against those cards, but it's a terrible choice because your opponent likely doesn't have any minions for you to trade into. So your "choice" often becomes not playing anything, which is effectively non-interactive.
