I’m a huge fan of role-playing and I couldn’t disagree more.
We’re essentially a super hero there to save their entire existence. Not just one covenant, but ALL of them. Combined with the fact that once we pick a covenant, they have us going off to help the others, there’s just no lore/role-playing reason why we (as The Maw Walker) wouldn’t be taught and allowed to use any and all abilities that they can teach us in order to kill the common threat.
Imagine if Green Lantern showed up to Earth and was willing to help all humans against the fight against Climate Change. This country specializes in wind energy. This other country specializes in Solar Energy. Another in water energy, etc. And then we told the Green Lantern “ok you can help us, but you can only align with one of us and use one of our types of technology at a time. And if you ever want to use another countries technology, you’ll have to go through an arbitrary 2 week grind to ‘earn our trust back’ even though you’re the one doing us a solid by trying so save our entire planet.”
The whole lore/RP argument FOR the restrictions is as sad as arguing that smoking tobacco is good because it helps us inhale/exhale more. It’s a joke at best and disingenuous at worst.
