We have arcade versus, wherein there are additional functionalities for the mode- we have map building escape wherein there is a great capacity of customization of the experience.
Will you consider adding an Arcade Horde?
Some extra functions for the mode could be things such as:
Extra modifiers, akin to the gears 3 modifier board
Health level controls by percentages (ex: enemy health: 10%/50%/300%, etc)
Damage level controls (One shot one kill enemies, players, 10%/50%/300% etc)
Selection of enemy sets in play and which spawn each interval ( deebee/juvie imago/ leech drones) Switch interval(enemy set changes every 1 wave, 3 waves, 5 waves.)
Legacy enemies (locust, lambent, etc.)
Enemy run speed/ player run speed
Respawn limit
Ammo modifiers (infinite clip, infinite ammo, 50% 200% etc)
Enemy density control either by percentage or enemy count
Legacy Bosses
Boss controls (Which spawn, count, interval - every 1 wave - 3 wave - 5 wave)
ETC
ETC

You get the idea. A more customizable horde experience mode where exp could be limited or altogether removed.
This would offer so much mindless fun, and attract so many people back to the game. This could really help you guys get the community back on the game.
I know in gears 3, we had a fierce love for the custom fun crap you had there like big heads, meteor roadie run.
If we had a fun, make it ourself, screw around horde mode to go cool off in after Horde wipes, bad versus experiences, too much or unsuccessful escape farming - it would probably go a long way to keep some of us on the game more often as well.
Come on TC GIVE US THE GOOD STUFF, GIVE US ARCADE HORDE!
Special addition- An option to bypass the hero system could be added to this mode!!!
It could be very simple- pick your character- pick the character card set you prefer. Allow multiple of the same set, and add a toggle for set locking for the host! Simple, easy way to offer players a way to play outside the hero system!!! <<<

of a time! A great part of that enjoyment comes from the Skill Cards; having interesting mixes of characters with different abilities. To strip away all of that uniqueness would be a massive step backwards.
