As a huge Battlefield 2 fan (but not Squad/Arma) should i preorder to try it out closed beta?

I was huge Battlefield 2 fan back in a day BUT not so much into Squad/Arma/Hell let Loose as it was too much walking,too slow with maps being too big.

I dont know if this game feels more like BF2 or is it simulator like Squad/Arma/HLL?

I was thinking about preordering game to play closed beta but time limit to refund is only 2 hours and i dont think i could have enough time to "test" the game to not exceed 2 hour playtime limit for refund..
