Things we want to see in Andromeda 2

Joke's on you, buddy. Drack is tied directly to Ryder. He wouldn't come back unless s/he does. 

Ok.

Other than what you've pointed out.

That the world = DA:I

and

Ryder = Hawke

We have.

Monolith = Solve puzzle, light beam which points the way to the other beams when all three beams are lit thry lead they way to the final site = Astrarium (don't make post videos.)

Formula = ominous bad guy you never meet who wont tell you about the mysterious big picture while you unlock the puzzles explore the big open zones and collect the treasure. In order to stop the ominous bad guy from attaining what he wants. With a mount/nomad for travelling, gathering crafting materials along the way. Loot is the name of the game in this world.

Corypheus wanted the mark to open the veil and conquer the world.

Archon wants Meridian to activate the vaults and conquer the cluster.

DA:I Mark key to opening the Veil = SAM key to opening Meridian.

Scourge, better be careful of that stuff it seems a lot like Red Lyrium.

Kett better be careful they sound like Qunari.

Angara sure are a lot like elves with their ancient glorious past they're trying to recover.

Roekaar v Resistance, mages and templars.

Rather than gathering a squad of allies and bringing together a group to do the impossible you're forging alliances between kingdoms and feuding factions to overcone the grand overlord whos so much better than you that hes not going to tell you how much better than you he is.

You're the Inquisition.

Bring back Shepard.

Not sure I would want him back anyway after the way they have handled Andromeda. 1 and 2 were magnificent games, hell 3 is better than Andromeda even with the endings. 

All good, just my opinion, I respect yours. 

There's a lot of good ideas already but the main ones that stick out for me are...
Other Ryder as a Squadmate
Day/Night Cycle
Enemies using squad tactics
Give us back control of our squadmates
