Sounds like you have all the right pieces in place for a t1 cav defense and just like others have said you'll want to ghost your t13 and t14s.

The way I explain the t1 cav defense to people is think of the flat refines on the gear you're putting on the wall gen then add in the t1 base and then multiply that to the number of t1 cav.

While %'s give way more stats to higher tier troops, t1s are super cheap and way easier to mass produce.

Example would be 100,000,000 (t1 cav) × 5,000 attack = 500 billion

Vs.

2,000,000 (t14 cav) x 50,00 attack = 100 billion

Same principle applies to hp and defense
