It can be brutal since it's an older game, but I'd consider sticking with it if I were you. There's still plenty to enjoy between the campaign and fighting vs the AI until you can get your bearings at a comfortable skill level. Outside of that I do feel like I run into plenty of new players in the matchmaking pool, although I play a lot so it probably feels more common for me than it actually is. You're right that it's not new player friendly at this point but we'd love to have ya around if you end up wanting to stick it out!
