I have 30+ HH and I still feel I am short on good heroes.

Now trying to decide which is better for me when I hit a lv16:-

1. Cav Phase
45 waves of warbomb or 5 waves of Layered Archers wave? I had some conflicting kill rates on the cav with my test archers waves. But think I need to test this again with 125k, 150k and 188k waves. One advantage of warbombing is I do not need to send those smaller warbomb. Now that we can draft again, I think this is no much an issue. But taking up 45 rally spot slot and heroes is the main issue here.

2. Archers Phase
6 x pure archers waves or 3x mixed archers/ball (100k archers + 20k ball) waves. Overkilled or I am too optimistic with my kill rate. (600+ attk HH)

3. Brute Force Phase
How many waves before the mech breaking force.

Any suggestion?
