I used to go with 6 heavy tanks 8 fighters and a few specialists and throw away, but a couple of incomplete attacks can set me back over 18k in oil to retrain. I now have a new strategy. Less is more.
I avoid all defensive troops (well most) altogether by using 2 transports and 2 fighters both are maxed out and the fighters enjoy 51% boost on damage and 12% on hitpoints. Tried it with boost artifact to paratroopers but did not work as well.
Pros:
transports have pretty large hitpoints and paratroopers don’t spawn defensive buildings plus they have both high hitpoints and high damage. A single paratrooper stand toe to toe with low level heavy tank and win because higher rate of fire. Drop them in groups of three they can destroy just about any building in a second except for one.
Since they don’t spawn defensive troops there are much, much less problems you have to deal with, you just have to make sure that you drop them on the antitanks or send your fighters to take care of them first. In addition even the strongest wall can be taken don just as fast by a couple of them.
Paratroopers also enjoy the benefits of armor and weapon blessing and as long as you don’t drop any barrack troops yo can re-use the same 2 blessings over and over again.
Cons:
they are slow and you have to wait in between drops.
While 8 fighters can feel a bit overkill but 2 is definitely fall well short of what most of us have become accustomed to.
The heavy tanks Hanks and anti-tank can ruin your day if you don’t plan ahead and take them out beforehand. Paratroopers don’t prioritize their targets it’s whatever closest to them.
Damage to town center get 85 percent reduction so it takes a while.
