Game is still too similar to Dota. They need to lean harder into the shooting mechanics. It feels like you're using pea shooters. Here's my suggestions:
>increase damage and decrease respawn time or down time
>every projectile has infinite range on every objective
>simplify last hitting, remove the floating orbs
>simplify the objectives, the stomps and so on are confusing for beginners
>give a more convenient way to heal in lane (similar to tangos in Dota or shrines)
