I'm gonna go out on a limb here and say that all defense (except hangar defense) is useless. Turret platforms can't kill anything. They just get popped one by one. Phase inhibitors are mostly useless, too- all they do is slow them down by a few secondsG. I understand there were issues in beta, but seriously... I'm really, REALLY tired of people phase warping around the entire system with 200 ships, completely unhindered. And don't tell me about ion bolt- that is one ship for one race with a low range. Repair platforms are nice but what use is it when they can just go around?
Fixes:
1) Boost turret DPS. Not by much, but something that makes the 75 metal worth it. They have terrible range!
2) Change phase inhibitors. If it was my way, they'd completely stop jumping. I understand some people don't like that, so what do you suggest for a solution?
3) Give turrets a bonus against capitals. Capitals have so much HP that they can laugh off just about any number of turrets. A small buff in this area would do some good.
Who knows, maybe instead of meddling with defenses they should just make phase inhibitors stop jumping entirely. That'd be a big buff to defense. Atm though it is pointless because you can just go around it nomatter how well-defended a position is. That is stupid.
