Everything Wrong With Mass Effect 3 Redux by GCN

Because even with that improved firepower, the Reapers' offensive and defensive capabilities plus sheer numbers made them impossible to defeat conventionally. Even if you have superior weapons, that doesn't mean you'll win. We have many wars throughout history that prove that. And Reapers aren't technologically inferior like those cases. 

Yeah. Like how Shepard stopped Saren and Sovereign from overriding the Citadel to open a portal for the Reapers, and destroyed a Mass Relay on the Bahak System to prevent the arrival of the Reapers. So all of that hard work that Shepard and Crew has been for absolutely nothing, because the Reapers invaded the Galaxy anyway.

They could've played Dragon Age: Origins and learn from it to rewrite the Reapers, and to write a consistent story. Because the story of fighting darkspawn was a hell of a lot better, than the story of the Reapers.

that is the spirit....Bad bunnies are alright with me,  Psycho bunnies are never a good thing....

who doesn't love him? Lets face it, he is very funny.

There are a lot of variables in how much damage Shepard would take falling from orbit. It wasn't earth so how going through the atmosphere could be different, what terminal velocity is may be different, how well armor designed to stop small projectiles being fired at near the speed of light would react to it we don't know. Given what the armor with its shields routinely deals with I'd of had 0 problem if a orbital drop just knocked the wind out of him.

Ah yes, everyone wants to nit pick Witcher 3 to death and point out all of it's small, unimportant flaws, but everyone just should ignore Biowares small nit picky flaws....makes total sense sir. 

oh wait...

Again, the writers didn't confirmed those details how Shepard's body survived from crashing on outer space. And it's highly unlikely that the armor is durable enough to protect the body from disintegration, and the shields didn't protect the body from being "meat and tubes". So, Shepard's death is very poorly written and it just use for shock value.

The Hades Cannon is still Reaper Tech and can one-shot a Human Reaper-Hybrid if you use it in game. They could've out fit their foot soldiers with heavy weapons that are effective against Reaper Destroyers/ Slaughter Ships to take out as many of them as possible. Also, they could build frigates that are fast and agile to take out Capital Ships with Thanix Cannons.

They could've create ways to turn the tide against Reapers with strategies and tactics during gameplay, and quests to gather, protect resources from indoctrinated forces, and they could create an actual super weapon to actually wipe out Reapers from existence. Instead of a plot device with a star child that makes absolutely no sense why it decides to kill organics, to "save and preserve" organic life.

It wasn't for nothing, it just wasn't the characters being able to stop the entire Reaper invasion solo.  You had a small delegation on the Turian homeworld led by Garrus and Admiral Hacket and other mentions of the Alliance were working on defenses as well.  Not to mention the additional time they delayed the Reapers for the way I understood the story pretty much at the end of the Arrival DLC the Reapers would have arrived, but since Shepard destroyed the system it delayed them a year.

The thing about the Reapers at least from my perspective and this is probably why they suffered is they weren't the main enemy they were always the background threat, even in Mass Effect 3.  Looking back in Mass Effect 1 the entire game was about stopping Saren and oh year he was controlled by the Reapers.  Mass Effect 2 was stopping the Collector's and oh yeah they were remote controlled Protheans.  As I mentioned above Mass Effect 3 was mostly about stopped the Illusive Man and his actions to help The Reapers.  Then you had the big fight.

Just going to put this here as well.  BioWare has always stated that Reapers were not stoppable by conventional means.  Sovereign was destroyed due to his "death" versus Shepard leaving the ship defenseless (at least how I see that).  With even the destruction of the Reaper on Rannoch it took the entire Quarian Fleet and the Normandy all synced together to hit at the same time.  So it was like taking a butter knife to chop down a tree, for eventually you could chop it down the problem is would you have enough time to do so.  So they aren't immune to our weaponry so it can do damage, but you first have to find the weak spot such as what happened on Priority Earth and then hope you can get enough time to destroy it.

Sovereign was defeated because Bioware wanted the itsy-bitsy-teenie-weenie frigate make the killshot. Even after the reapers shields were disabled, it still wasn't taking any damage until the SR1 fired. At that moment, it became the most powerful ship in the galaxy.

Entire fleet? No. Just because Shepard says entire fleet doesn't mean the entire fleet was firing. It was more like 5 maybe 6 ships firing at the reaper. The whole sequence was lame. When the reaper is first fired on, Shepard says its weak spot is the firing chamber when priming. That's incorrect. The rounds hit the reaper before the doors are opened. The destroyer falls to its side. At that point, it appears to be out for the count. But due to the power of plot, it rises. It gets shot again, but this time it doesn't fall over like it did the first time. Why? It's only after the reaper and Shepard can kiss each other that it falls over for good only to say you do not comprehend.

The writers don't confirm the details of most of the space magic they use. You say its highly unlikely, I think its highly unlikely he took as much damage as was portrayed in the story.  Its inconsistent with what the armor routinely deals with. But, they have a lot of inconsistencies with their armor/shields. And yes, it was poorly done and just for shock value. I don't think anyone disagrees with that general point.
