OK so here's my suggestion but feel free for anyone to disagree.
- Use 2 Diegos + 1 Alan + 1 La Quica
- 4 squads of Flacos should give you a total of 61 Flacos
- You need to constantly use guerrilla flacos + the new ammo factory to optimize your attack
- Before deploying you should focus on destroying buildings with your missile that are effective against Flacos (Rocket Launcher, Machine Guns, Mortars)
- If I'm correct you should be able to destroy an Rocket Launcher around your level in 2 hits with the help of your 2 best Diegos
- Take advantage of buildings that sit next to each other (horizontally, vertically, or diagonally), you could hit up to 4 buildings at once if they are situated poorly, if there's a sicario standing next to a building you want to destroy you could also target both at once as it gives you even more energy
- Considering there's no Maeve, for each building you destroy it will give you 4 energy thanks to your La Quica, imagine if you could destroy 4 buildings with 2 missiles (you could recover up to 16 energy in total)
- By the time you're ready to deploy, make sure you've still got some energy left at least enough for 1 flash
- Try aiming your flash at a few buildings at once, the more Big Bang you have the more damage your Flacos will inflict to buildings affected by flash
Deploying is about energy management these days. The more efficient you play with energy, the more effective your attack will be.
Also I'd suggest to prioritize on your offense first (Helipad, Squad Camps, abilities, troops, offensive sicarios). Don't level up if you don't have to. The key is to be able to raid anyone on your map before deciding to level up. Defense could wait until you find a perfect balance for your offense.
The best troops combination I've found so far for level 50 players and below is 2 Gordos + 2 Fuegos as they work just as well with any of the missile squad, flashbang squad, or firebomb/energy squad. If you play it right you'll get close to no casualties so there's less waiting time to do your next attack.
