They have been, since I started playing, but as of late they don't even seem to be able to kill a squishy.
If I have fewer HP than an opponent, I leave the turret, because it simply doesn't help enough. Competent opponents know this, and they abuse it.
The damage seems to be fine, but the response time from the turrets has been a joke since I started playing. Please fix this.
I don't think that a squishy should be able to hold a point against 3 opponents, but I do think that a squishy on their own turret v. a squishy pushing that turret should have an actual advantage.
It's too easy to get damage in early and get a kill on an opponent's turret or chase them off and cap it.
Please fix this. This isn't the first time that this has been complained about.
