Hey everyone 
There are sooo many ideas about Borderlands 3 here already, i’m sure that i will repeat someone’s idea, because i can’t memorize them all
So, i’ll simply write everything i have on Borderlands 3 (ofc i will forget something) Oh yes, is it ok, if i will write Borderlands 1 and 2 like this B1 & B2? Thanks 
Campaing
So, the main idea for the campaing itself. As we know, some war is coming, which means, that B3 need to make something bigger that fighting the Vault guardians. I think, that there could happen some kinda “parade of planets” or the universes with the planets, that have vaults (We saw it in the ending of B2).
So, a lot of planets will be in the line, which causes the trans-planet portal or area between it all to be open. This area is the place where all the biggest fights will be encountered(like final boss or bosses, i think that it is possible to fight 2 or more vault guardians at once, and in the end fight the biggest one)
Of course, it all will happen on Pandora as it is in the middle of all of it. Pandora is a big planet, and i hope that we haven’t discovered its all secrets and locations.
Locations
First of all, i hope that locations will be logically conected to each other. Like it was in B1. In B2 and TPS i don’t feel that i’m in the same world by constantly fast travelling or even walking to other location. In B1 it when you proceed to next area, it still feels that you are few meters from the place that you have just been in. In B2 you start in snow location, then get to the Sanctuary (No sing of any snow), then you go to the dust just walking through the door (I know that by the story it takes us few hours to get to the dust, but still, i was in Snooow map and now i am in the desert wtf)
Maybe some underwater locations with their own vechicels, and on water fights could be awesome.
Weapons
I think that there must be an option to upgrade your gun. For example: You pay Marcus and he sets on your gun a scope. I hope everyone played call of duty or similar games, where you can choose what to put on your gun, stock, grip, extended mag and so on. In B3 i think it would be nice for you to make a bad weapon into good one.
Elemental weapons. Nothing much to say here just i hope that there will be all elements from previous games (I didn’t play much TPS, i really don’t like, tried few times to start it, but i just done like that
).
So lasers should be in. Cold elemental weapons could be awesome. Imagine that you attack enemy with cold elemental gun and it slows the enemy(they will walk, react, shoot slowly). If you freeze them too much, then you can break them like a glass. It is like slag weapons 
Meele weapons should be in the game, i think (axes, swords, claws…) 
Armor
I’ve always wanted to improve my defense in Borderlands. Sooooo maybe armor pieces could be added
They could even affect some skills.But also it is a good way to change your character appearence (or in case you dont want to see armor, there must a button which makes all the armor invisible)
Good idea, right? 
Characters
Scooter. Well, we all think that he is dead. I’m sure he is. But there too many movies and games where the dead guy comes back, i wouldn’t be surprised if Scooter is alive. Buuut i have a better idea for this. Scooter-bot. It’s a robot with Scooter’s mind (i guess he probably uploaded his brain to a hyperion robot, or some did it, or Scooter desinged a robot to act like him).
Sirens. There are 4 of 6 sirens in game (which i know). 1st on was killed in the B1 in the end(don’t really remember her name). 2nd is Lilith. 3rd is Maya. 4th was Angel. So, i think that 5th one must be a playable character. And the 6th could be a very badass boss. The siren who can controll all elements and have some more coold powers (fly, teleport, telekinesis…)
Playable characters
Well, all from the B2 should be still playable, maybe even characters from B1 too, but i’m not sure if that’s a good idea.
Here a some of my ideas for some new character’s abilities.
Teleport: When you activate your ability, you can teleport for a short distances few times. It can save you in battle, help reach high ground, reach far standing enemy, or get in the middle of the fight.
Slow time bubble: When you activate this ability a big bubble around you will appear for a short time and it will move with you in the middle of it. It’s radius should not be big (20meters), but everyone who gets in it (enemies only) will be slowed soo much, that you will actually be able to see bullets and easily dodge them.
I had more ideas about new abilities… can’t remember them all right now 
SO! I think that this Borderlands must be a 8 players playable game. 4 players split-screen ofc. But let’s image how cool could it be to play through the campaing with 7 friends online. Of course, the game should get much harder when there are 8 players, so that you will have to think about strategy and how to combine you charater’s ability with other charaters and weapons and so on.
Hmmm… i am sure that i had muuuuch more to say about B3. But that’s it for now ))) Hope you will understand everything i wrote here (I speak english really bad, but i did my best here)
