1 - Indeed you can. But, none the less, it will not make you immune to it. You can end up flying ships you'd prefer not too in an attempt to tank yourself up - which is a shame in itself - but even like this, there's not much to be done when one or more fully engineered ships decide to blow you up for their giggles. Ultimately it seems a shame when a majority need to compromise their experience and fun due to a toxic minority wishing to play cynically.
Engineered mini maxed player combat ships are far to overpowered(PvE and PvP). This removes the danger aspect for those that bother to build them. This opens the door for giggle killing of both players and NPCs.
These ships are as you say, not something most players want to fly. They are only good for killing.
It is poor game design to allow players access to ships with such properties. Particularly in a game like ED, where combat is a central part of both game play and mythology. Combat focused players will naturally gravitate towards such builds. Either because of the competitive nature of pure PvP or because of the cr/hr focus of many result oriented PvE players. Thargoids make that pull even stronger.
There is absolutely no reason to allow the level of tankyness we can have today. Countering this with extreme weapons, just makes the situation worse. The tankyness is also the reason that ramming used in many situations.
Unless combat builds are balanced against other forms of game play, the combat aspect will suffer. PvP is all but lost all ready. When you need a PvP hub with special rules of engagement, it shows how detached it has become.
PvE combat has received the Thargoids as gift to those that need some content for their over powered ships. PvE bounty hunting is not about wining fights, when you fly an apex build. It's all about speed of kills.
Yesterday, I actually tested the Obsidian rescue missions in open. It was a quiet experience. Two combat ships were hanging about the rescue ship. A Corvette and a FAS, I think. I spotted a couple of ships that seemed to do the missions as well, but not many. No shot were fired, no one tried to ram me. It was more a cold spot, than a hot spot.
I bet I would have seen twice as many, if did the run in the Canonn PG.
Poor balance leads to boring game play that people opt out of. Ramming is typical poor game play. Adding more passive defense to avoid dying from it, does not make it more fun.
