The people from the milkay way.....

Yeah the story line was incredibly weak, IMO.

It would have been much better if "Scavengers" just didn't exist.
At least not in the volumes that you see. If you want one or two cells of "criminal" types that sneak off and do their own thing, fine. But not this mass scale exodus from the Nexus that was observed where you have hostile "Exiles" every 50 feet on every planet you explore. That's just dumb.

I guess the only thing that slightly makes sense is that all the strong leadership died. But even still, having full scale faction wars when you are being actively hunted and exterminated by a stronger alien enemy is just stupid and unrealistic. It's not hard to figure out that surviving depends on unity. You can overlook any differences if survival is on the line. History will show you that time and time again.

It would have been much better if one of the Arks was captured and all the inhabitants were exalted and the scavenger units were just turned into Kett units.

The diversity of enemies was extremely weak as well. There were only 16 types of enemies in the whole game. Of those 16, 6 of them are just red bar trash mobs that are basically reskin'd clones of 2 enemies (each faction has a basic melee unit and ranged unit). Each faction had one or two "medium enemies" and one or two "ultra" enemies. Of the ultra enemies, the only ones that seemed to have much effort put into them at all were the Ascendants. The rest were like "Just give them huge armored hp bars and some guns or melee attacks, they'll be hard because biotics can barely scratch them and the player will run out of bullets".

The ending was disappointing. It lacked gravity and consequence. The choices you made and the thoroughness of the play-through seemed to have minimal effect on the conclusion. You can tell everything was just set up to fit nicely into a DLC coming soon.

I still liked the game. But it was a massive step in the wrong direction compared to the rest of the ME series.

I will give a shout-out for the new "build-your-own class" system. That was well done IMO.
The R&D weapon crafting system was also very good. No complaints on the diversity of skills or weapons or character customization.

I just wish that I could take my tuned-up Ryder against a more diverse and interesting set of enemies and have those enemies be someone that it actually makes sense to shoot.
