Just a thought, it would make for a pretty epic time. Having a 5 person team hold a point against an increasing horde of anything would be a great way to learn the workings of individual Battleborn and give teams an opportunity outside PvP to practice working as a team.
That could be pretty fun actually! Who doesn’t love a good wave defense mode! 
I’d play it, sounds like a good way to try and find a good team comp, looking at both the players and the heroes you choose.
Throw in the ability to play this solo aswell and I’m in on this idea.
Sounds like a great idea.
A lot of people have already suggested a dedicated Wave Defense/Horde Mode, myself among them.
More PvE = Good
I am pretty sure at least of one of the six missions that we couldn’t play is Horde Mode. Even if there is not, I believe they will create one as a DLC.
I think “The Renegade”, the mission that unlocks Caldarius is a Horde mode mission and if I remember correctly it’ll be the third mission according to the greyed out info in the beta test.
My own personal opinion would be a more dedicated game mode with numerous enemy types and multiple maps would be ideal. Maybe if we poke Gearbox they will consider it after the game is released? 
I vote for this, it is definitely a good idea. GearBox please make this a game mode.
Without a 5-man team, it was rare that either of the playable missions in beta lasted long enough to see my character reach level 10. I’d love an endless horde-mode just to actually be able to play around with the abilities of a capped-out character for a while, and go to town on a ton of bad dudes with upgraded ultimates and over-the-top team combinations. 
A la, Plants vs Zombies, sure, I on board with that idea.
+1 for this idea. Makes me think of ME3’s multiplayer, which was so much fun.
horde mode mixed with tower defense and our bots sounds like a amazing friday night with friends
im all game for more Co-op ideas with my friends rather than comptived PvP
