I've never had a problem with established IPs being turned into mobile games; mobile isn't inherently bad and can be a good platform for interesting twists on certain games. Complaining that a game is mobile just because of the platform is idiotic.
The biggest problem, which you highlighted, is that mobile is becoming synonymous with microtransactions, especially for certain companies. EA has a history of taking established IPs and completely bastardizing them on mobile to essentially strip the gameplay and replace it with slot machines or timers.
A game can be interesting and fun, but if that ugly side of mobile rears its head, that's where the massive disappointment appears. I don't trust EA and no matter how much fun an IAP-free hands-on is, I won't be excited until I see the final product and how purchases are handled.
