LTM idea-(insert catchy name here)
This isn't exactly a new idea, it's actually something I remember seeing in Fortnite a long long time ago (yes I'm a OG there and played it before it was cool 😛 ) it's a simple concept but should make for some pretty interesting and epic battles.
Basically what you do is split the lobby into two, keep the teams of three so there's still room for cooperation since letting everyone hear everyone else's pings wouldn't end well, then drop both sets of teams on the opposite sides of the map using two separate dropships and let the match play out as usual with the exception of it's now 30 Vs 30 last man standing. You can see minimap markers of nearby friendlies and can communicate with them using ping wheel if you're close enough (like proximity chat), you can also revive allies from other teams like in shadowfall event, this will encourage people to work together and stop matches from ending too fast.
Only thing I can't decide on is if teams are eliminated after all three are knocked, or if allies can still get them back up, this would give even nub teams a chance though so there's that. Feel free to add any suggestions of your own.
