Shadow of War: Microtransactions?

Shadow of War is a fun game. As you play, you find yourself constantly fighting, running, and dominating Orcs in order to create your own army to save Mordor. The story is great so far and there's almost nothing wrong with the game. Let's get down to the Fortress Sieges and Defenses. They're fun, it's really cool to see the orcs you've dominated take charge and attack an enemy fortress. It's interesting to see that your Orcs use their abilities in battle to fight the enemy and get to the Overlord. It's all fun, but as I play through these missions I can't help but wonder, "Will this be fun after about the 20th time in a row?"

I haven't beaten the game, but in order to get the True Ending, you must go through 20 Siege Defenses in order to get the real ending. "Wow!" I said. I think I'd get bored doing the same thing over and over again to be honest. This brings me to the microtransactions. In the menu you can buy crates to get orc captains and some equipment. So I looked at these chests and decided to get the free loot chests that consist of using 1000 of the ingame currency. I bought it and got two level 15 orcs, one of them being Epic ranked of course but, weren't useful at the time and I decided to ignore it. Now that I look further, there are things like, class-specific war chests that can give you things like two assasin orcs and some training orders that help you level up your orcs for about 240 gold coins, that's about $3.00. "Who cares!?" I say. Why should I buy any crate when the whole point of the game is to create your own experiences of dominating and killing these unique orc captains?

If anything, I'd stick to the "free" in-game currency chests, or simply fighting orcs, that's way more fun. Maybe I'll just watch the ending on Youtube, so I can just play the game near the end, for fun. I do not condone buying loot chests with real world currency and I do not wish to see it in a single-player gaming experience.
