The name of the game is HKs, so people will get HKs and they will make it efficient.
The system could have been fixed by now with endless solutions such as HK cap per player per hour, equipment degradation at death, removal of AV, awarding HKs for completing goals in AV, going back to a honor system etc.
What's happening now in AV is breaking no rules, people are simply low skilled and they know no better strategy than charging ahead on the bridge.
Luckily this is enough pvp skill to get pvp gear in the current system.
They don't use 3rd party software, they don't use exploits, some use scripting and soft botting (multiboxers) but that's apparently ok, so really no rules broken.
