then do not use them

btw how to use them is to separate them very far from the portal, however, the projectile causes a lot of lag, especially if you are continuing from a location

Maybe rainy could do it this way that these Tower spawn a projectile every round so no issues will appear.
The only thing would be is to buff them because they can only send one. Tesla : maybe double/triple damage.
Freezer: maybe multiple hits or much longer freeze

Abilities were reworked in many updates and I believe they are quite useful at this moment, closing the issue as resolved
