As title, i have a little suggestion that if flare can add features on different landscapes so that we can pick different landscape with different troops and towers accordingly. Mostly pick burning rocks because it is dark so difficult to see with low quality mobile phone.
Below is example,
Burning rocks = 2% fire damage on attacker & 0% on defender
Haunted forest = 5% movement speed on attacker and 10% on defender
Northland = 2% slow (attack & movement) on attacker & 0% on defender
Highland Meadows = 5% regeneration on attacker & 10% on defender
Christmas woods = 2% ice damage on attacker & 0% on defender
Golden desert = -5% regeneration on attacker & 0% on defender
Mostly 0% to defender because they use to the environment where they stay with.
Sorry for if anyone suggested this and for my bad english.
