Isn't it a bit soon to decide if this is a good expansion or not based on just the MSQ and 2 EX trials?

We don't have raids yet.

We don't have Cosmic Exploration yet.

We don't have the new exploratory zone yet.

We can't start the relic weapons yet.

We don't have the new Variant/Criterion dungeons yet.

We don't know if the trial series will go back to being a separate thing or will once again be baked into the MSQ.

We have no information about Expert crafting yet (I'm guessing it will be part of Cosmic Exploration?).

We don't have the treasure dungeon yet.

We don't have the Ultimate yet.

Definitely it's fair for players to say "so far I'm enjoying/disliking it" but it's really premature to say that it's a great/good/decent/mediocre/bad/terrible expansion. We haven't seen enough of the content yet to decide.

Someone should bookmark this then come back to it in 7.5 to see if feelings are still the same.
