It'd be cool to see a new unit with a time stop ability. For example, if you upgrade a specific tower which would have timestop ability to lvl 3, you'd be able to stop every ennemies in the tower's range for like 3 seconds and the ability would take 14 seconds to be activated again, so 4 of this tower would be enough to settle an auto-timestop cycle. To make it automatic, we could also add a button on each tower to make him auto-activate his ability. Btw, the ennemies affected by timestop would have a marker on his health bar, so he won't be stopped until he dies.
We could also add burning or bleed so few towers would be much more stronger. For exemple : if the tower deals 400 dmg per shot, his burning dmg would do 40 dmg every secs for 10 secs, so it'll be 400 total burning dmg. The 10secs or the dmg are only exemples.
So we could add :
- timestop ability
- button to auto-activate any ability for tower of our choice without having to do it manually
- burning dmg, so even if the ennemy isn't in the tower's range, he would still receive damages.
Sorry I spoke a lot
