It's kinda cheating because I'm still working on the final DLC, but this one won't take me too long to complete. So far, Shadow of War is a lot of fun and can feel a bit grindy at times since it forces you to go back and fourth between regions and by the time you revisit a region, all your old captains are vastly under-leveled and need to be either upgraded, or culled to make way for new captains. The only main gripe I have with the game is that the bosses (ie. final bosses, not warlords) are just QTEs with extra work. Most of them are "Dodge X attack three times, then perform an execution, then repeat Step 1 until boss is at 75% health then dodge Y attack three times, then perform an execution, then repeat Step 2 until boss is at 50% health...". Granted, while they are just QTEs with extra steps, most of them don't feel like QTEs or a chore to do like most QTEs in the past.
That being said, I would still greatly recommend Shadow of War to anyone who is a fan of The Lord of the Rings or just third-person action games in general. The vast majority of the game is a lot of fun and allows you to decide how to tackle most encounters with a fairly varied skill layout that gives you plenty of abilities to use. Not just abilities for Talion to use, but you can also use the environment to your advantage (and in many cases it's necessary) so most of the encounters fighting captains, war chiefs, or warlords, rarely feel the same. Not to mention WB really outdid themselves with the different styles and abilities you can find on ork captains. In my 130+ hours I've played, I'm still finding captains with traits and abilities I've never seen before. Edit: Just don't expect a lot out of the online fortress battles since a ton of people used trainers to make their orks virtually invincible. There's a good chance you'll end up fighting a hacked fortress or a really low level fortress - there really is no middle ground here but you don't miss out on anything by not doing the online conquests. They're just extra fluff quests that aren't required for anything.
As for the DLCs, Eltariel's DLC was fun for a while, but there were more than a few times that it pushed me to stop playing for the night. It's really linear which isn't a bad thing but some of the legendary item captains took a really long time to kill just because of how they are set up. You can probably blow through this DLC in five to ten hours without much issue and without skipping anything, but the final boss encounters were easily the worst part (see above for QTEs). I'm still working my way through Baranor's DLC and it's a lot more fun than Eltariel's simply because it forces you to take encounters a lot slower and utilize everything to your advantage so you can have the upper hand at all times. Since Baranor doesn't have a ring of power, he can't dive off 400 foot cliffs and survive, so you'll have to use other means to travel around (I won't spoil it, but you meet a familiar face from the first game: Shadow of Mordor).
Edit: I forgot the most important part: Play on Nemesis difficulty. It's definitely worth it and it's not that difficult. I honestly don't understand why there's lower difficulties since the Nemesis system really only makes the early game difficult. Later on when you have a plethora of skills to use, the Nemesis system just adds an additional layer of fun to the game.
Edit again: Finally beat the Baranor DLC and it's far more fun than the Eltariel but it unlike Eltariel's DLC which gives you captains to use in the main game, Baranor's DLC is just for something else to do and hit a high score. It might not be everyone's cup of tea since it features perma-death (though you do keep all your upgrades and augments if you die), but it is a lot of fun.
