Just wanted to create a thread about this myself,but since the OP already did it for me,I'll just jump in.
Aaryn,listen to me man....
Priority:Earth was bad. Just bad. Ask anybody who worked on ME3,they'll tell you the same.
And honestly,I wouldn't even consider it a full "remaster" without at least some changes to P:E. A "Remastered Edition" doesn't include a broken story and new plot holes popping up every five minutes in its last mission which was supposed to conclude the trilogy in an awesome and epic way. It also doesn't (or at the least,it shouldn't) include re-used assets from the entire game,and the exact same soundtrack play over and over.
P:E needs an overhaul. If remaking everything from scratch is too much for you (though it shouldn't be),at the very least consider these things:
- Remake the map.
P:E had terrible,terrible maps. Most of the stuff you see is reused from earlier in the game,and there are literally two types of buildings used throughout the whole level. Its obvious,even to gamers who don't pay attention to stuff like that,that the map was rushed as hell. A more open,original map that would in terms of quality be the same as the rest of the game,with less grey colors and weird 20th century building, that would show us London like it was supposed to be: A war-torn city.
- A new soundtrack.
Priority Earth didn't include a single new soundtrack. In fact,most of the time there was no music playing,except during those horrible "survive" and horde modes to I guess,what,prevent the player from closing the game all together.
If you did it for the EC in less then 3 months,you can do it again for P:E.
- Fix those damn plot holes and story contradictions.
Here are a few examples...
At one point in the mission (just before sending Hammer to retake London),Major Coats asks Anderson if they can deal with the Destroyer using Air Support (since we have an entire allied,galactic fleet above);Anderson says no,since all communication is cut due to,quote "Some kind of interference from the beam".
However....during the missile defense segment,EDI somehow contacts Shepard and asks him/her if she can link the missiles to the Normandy's targeting system.
This raises a couple of questions:
1. Didn't Anderson just say all communication is cut. If its actually not,then the entire "ground assault" is literally pointless,since they could've taken care of it from the sky.
2. If EDI can contact Shepard,then why can't Shepard just tell her or Joker to simply go down and take care of the Destroyer instead of Hammer. Why go through the entire process if the Normandy can destroy the Reaper in less then a minute?
3. Lets say that the Normandy isn't powerful enough to do it by itself. Can't EDI just contact Hackett instead? We have an entire galactic fleet above us. Surely a few cruisers can spare a couple of seconds to fire on the Reaper guarding the beam.
Later however (and this was added in the Extended Cut,btw),Shepard contacts Joker directly,while standing next to the beam,and asks him from the evac of the squad. Again,this raises similar questions.
Another plot hole:
This may have an explanation,but it was never offered in the game. Its quite simple. 
So...this beam. It goes from Earth to the Citadel,right? Through space? And anybody who enters it gets transported to the Citadel?
This is the first thing that came to my mind when I was playing ME3 for the first time. What exactly is stopping Shepard (or in fact,anyone) from simply jumping to the beam from space? Why the need to use the beam specifically from Earth? There was never any console or a control panel in London that forced Shepard or anyone in Hammer to use the beam specifically from Earth. So really....what was the whole point of the assault on London?
- New "Hammer" cutscene.
Here's the current Hammer cutscene.
First of all,whoever edited this obviously didn't have more then 10 minutes to work on it.
For a cutscene that had so much previous building up to,this was extremely underwhelming,and simply terrible.
Its exactly the same no matter how high or low your EMS was or what you did in the trilogy. No War Assets,the "Battle for Earth" soundtrack (again),and awkwardly fades to black for no reason.
Making a new cutscene with variations shouldn't be an issue. Period.
So there....I'll probably make a thread about the whole issue and to sum up everything players want and to expand the list of suggestions.
So Aaryn,Mac,or any other CM or dev reading this. Please,consider it. That's all we want.
We aren't asking you for a boss fight with Harbringer (though it would be awesome to be able to take him down if your EMS is high enough),but some obvious things need to be fixed.
