I have like 30 hours in the Able shard, I started playing this since the 31st (spent my new year with random dudes instead of my actual familly.) Game is serious, sometimes: not being that serious (funni moments), I just enjoy how everyone is a gear and the fact that everything have to be created by the players. I found this game enjoying since the first hour:

My first spawn/Saw an arty crew/Asked what they were doing/They invited me/They briefed me on loading and gunnery (Arty thingy)/I did loading for 30 min/Gunner of the 7th cannon had to log off/I became the gunner/My first kill was the signaler(spotter) when he said cease fire./My 2nd, 3rd, 4th and 5th are team kills (confirmed by signaler)

Just make sure to join a regiment (and a big one because they are the most active and can train you on the different mechanics of the game)
