I have noticed slight imbalances with towers. I will list some, feel free to add to or criticize what I say!
1- Krelos
Where to begin, first he was the discount dragon. Which is completely fine and I love the concept of two weeks discounts. But how we can basically death gaze towers, evade projectiles, and complete runs in a very minimal time frame. Is amazing. But he is rather annoying to defend against since he’s The Godfather of all dragons.
2- Howi/Drakul
The howi is an extremely good tower for its incredible range and completely overpowered damage. I get you can blink the shots, but the rate of which it fires feels like a machine gun. Currently it is incredibly OP, but if you wait a couple tiers and seasons it should balance out, as seen with Sylvix.
The drakul is amazing for damage and I think dragons need to have a way to dodge beam damage. But like I stated before hopefully dragons will adapt for this. But with two legendary dragons in this season that can freeze towers I feel pretty good about balancing tower to dragons.
Again, feel free to add or question what I say. Have a great night/ day!
