I also have the free base-game ( It still is free till the 18th, i think ) on PC.
Honestly, it can be fun with friends but also gets old very quick. I can´t say exactly why. Maybe because it is all instanced and i just like open worlds/maps and a bit of exploring or just sandbox-elements. The events do spice it up a little bit. The story doesn´t really impress me but the cutscenes are indeed very good (The story would work better as a movie in my opinion). Haven´t seen a lot of the game (got to Level 15 or so) but there also was no moment when i thought “I wanna see the rest of the game/story!”.
But i had the same or similar problems with games like “Defiance” and “The division”. The games all lack of elements wich make them more “MMORPG-like”. The only game with (basic/simple) Shooter-Mechanics that worked for me as an MMORPG is still “Fallen Earth” because it had/has a strong MMORPG-atmosphere around it (Even if it is bugged, has bad graphics, bad animations and is overall very outdated):
Deep crafting, a lot to explore, huge maps, sandbox elements, a world that feels like a world, a good story wich works in text-form and has mostly no cinematics, nodes you can harvest, mops you can harvest/loot, camps/things you can build, areas you can control through PVP, players you can meet in the world and not just in social hubs, no level-sync, things to discover etc.
That´s basically what i wanna see as a shooter-MMORPG.
A MMORPG with guns, literally.
