Swarms of storm cannons on defense are a common tactic. But they are seriously overpowered, able to annihilate any troops from another lane, effectively removing reinforcements for the hero. There is no counter against them (at least not one that I have found). Players that spam them often have poor defenses otherwise, so storm cannons become an easy way out.
The boost makes the cannons shoot faster at the cost of damage and increases their health monumentally. Simply remove the health boost, or even make it slightly negative. It doesn’t even make sense for a cannon to have a lot of health for the role it tries to fill.
Battles in war have become boring and I’m always forced to attack low levels because everyone around my level just spams them. A good defense should be a reward for dedication/hard work, not the result of a single boost.
Sorry if this in the wrong section, it doesn’t let me choose on phone.
