I was playing on Incursion the other day and while our team was pushing our opponents and taking out their first sentry, a Kleese got behind us and I’m pretty sure he single-handedly took out our sentry. I don’t think any minions were back there helping him because, again, we were completely dismantling their sentry.
This kind of thing simply shouldn’t be possible and isn’t in a game like League of Legends. I really think Sentry shields should simply not be able to take damage until there are minions at least in the vicinity.
The recent changes to Incursion have been great and have really made it more important than ever to push minions and grab the Thrall camps. If we changed the Sentry shields as I’m requesting that would also help to further emphasize the fact that this is a mode about pushing minions and without them, you can’t succeed.
FWIW our team went on to win. It was 50-50 by the end but we had higher score because we got a lot more kills on them.
EDIT: Just going to edit to respond to a couple of themes I see coming up. Yes, obviously map awareness is a thing and we should have realized the sentry was under attack. However, in our defense the Sentry did not give its usual warning and that life bar is pretty easy to miss with everything else going, especially as, like I said, we were busy whomping on their sentry. By the time I ported back to base thinking “job well done”, I realized our sentry was under attack and we were too late to save it.
Also, here’s the main point. “Backdooring” the sentry should not be possible at all. That’s why I make this suggestion. The game is supposed to be about pushing minions, if you can kill the sentries without pushing minions then there is no point to them. I brought up League because backdooring in that game is nearly impossible, I mean, maybe late game you could backdoor a turret but even late game I doubt you could backdoor the Nexus and its’ turrets. This is good game design and I think Incursion in Battleborn should function the same way.
