The last two expansions are a bit underwhelming IMHO.
Gallipoli is ok, because those maps are at least included in Operations which is the mode I most often play.
At the moment the other Turning Tides (North Sea: Heliogoland and Zeebrugge) and Apocalypse (Paschendale, Somme River etc) are not available for Operations and seem most suited for Conquest (which I find dull). Don`t get me wrong, the maps look beautiful, and the new weapons/vehicles are welcome, but I feel I`m not really getting value for money if the maps are not available in operations. I haven`t checked if they are available on Frontlines yet, but on XB1 their isn't much of a player base for that.
