How about a new Play mode next to Troops & Loners; needs some catchy unique not copyrighted name (devs call your marketing department for that).
Game Mode is set to 1 Map only each 48 hrs until a new Event starts on a different Map / Campaign.
Map starts normal like Invasion;
when attacker captures either last Cap point or ran out of tickets, defender receives 1000 tickets, 5 seconds faster spawn (compared to new defender) and has to recapture lost points on the map.
If Attacker fails to conquer 2 capture zones at least, Attacker receives Automatic Bonuses of 1000 Tickets, since counterattack shall only be activated on 3rd, 4th or 5th capture zones when attacker fails and would include recapture of 1st & 2nd zones.
Basically:
1st cap - receives normal tickets if captured OR receives 1000 tickets if not captured
2nd cap - receives normal tickets if captured OR receives 1000 tickets if not captured
3rd cap - receives normal tickets only
4th cap - receives normal
5th cap - receives a “win” point
If Counterattack starts at 5th cap:
5th cap - previously defender lost this one, now has to recapture it, receives 1000 tickets, if fails another 1k is added.
4th cap - receives normal tickets if captured OR receives 1000 tickets if not captured
3rd cap - receives normal
2nd cap - normal
1st cap - normal
Counterattack 1st Cap is the traditional 1st capture zone on any invasion map, making the normal attacker the defender of his last capture point. Capturing it as Counterattacking team gives 1 win point.
This goes on and on, the Map doesn’t finish until the 48 hrs are over and win points are calculated.
Experience reward is only 5-10% of what normally is given.
The Side wins which conquered the most Cap points during Event ongoing. Making it a Community effort rather than just a Team effort.
Tanks are automatically removed; max 25 dead tanks in total on map, the 26th will always replace the 1st and so on. Also to save some RAM.
Unlimited Warfare, Artillery Spam is allowed, 2 Bombers at the same time, make it a test bed how Devs wanted Enlisted to be like and just fix Bugs but not Gameplay for this mode. See how it works out on the long run. Since it is more for people who want enduring action. Obviously some people may not like that, but we live in times with different opinions how game should be.
