This has bugged me since beta and I don’t see it brought up almost at all.
I will use Overgrowth for example. After you destroy the first sentry, if you push into your enemies area to their health station you can sit there at range and shoot the sentry down to 0 if you like without him even being able to fire a single shot your way…that just seems ridiculous. its like the first sentry matters because you need to be strategic and use minions, but the second one is just a pushover!
The map needs to be altered so that if you can shoot the sentry, he can shoot you as well.
