I agree with that. Until you choose to be the aggressor in BGS.
Which is a PvE activity, so you can attack and defend from any mode.
Everyone chose to play a mode for a reason. That reason can vary.
You don't need a reason to pick a mode, I sometimes pick a mode at random.
The most fun is getting the kids to load me into the game when I'm not looking, so I have no idea what mode or PG I'm in.
Some people also click the wrong mode and don't realise they've done it.
So people can be in Open mode (or Solo) without any reason at all.
And that's fair, I have no objections to that. I just find it rude if you choose to be an aggressor in BGS while using PG/Solo specifically to avoid contact with the one you oppose.
You find someone doing a PvE activity in a PvE mode to be "rude" - the problem isn't the game or them, it's you.
They are just playing the game, the way the game Devs say we can.
I agree; and that's exactly why I'm in favour of Open.
The BGS has nothing to do with the mode system, Open mode is irrelevant when doing BGS / CG work as people on other platforms, in other modes and in other Open Mode Instances can oppose you without you being able to see or interact with them. This was an advertised feature of the game.
So you need to update how you think about the game, you have an incorrect view of it and how it works.
If I oppose you in BGS I'm dictating how you spend your free time in a game you bought with your money.
No, you're not dictating anything, I can choose to engage the BGS changes or I can choose not to engage.
You don't dictate anything, it's my choice if I want to fight or just carry on playing and ignoring the changes.
There are lots of other things I can go and do while you play with the BGS, including letting others know there is a BGS "war" going on so other people can jump on it.
What I find rude is people who chose to do that in a way that they can be anonymous and with no chance to suffer any consequences for trying to dictate how I spend my free time in a game I bought with my money.
But the BGS was a feature you knew would be affected by all modes before you bought the game.
I know you knew that because of right from the Kickstarter pitch before you could buy the game it was advertised and it still is an advertised feature all these years later.
The link in my Sig has all the historical information on it. So I know this to be true. You knowingly paid for a game where others can attack you via the BGS and you never see them, you paid for that feature on purpose.
Therefore you can not be "forced" to do anything regarding the BGS as you paid for a game where other peoples actions in other modes and on other platforms and other instances will change your game and how you play. You specifically bought that feature, so it cannot be rude for people to play the advertised feature.
So we are back to my above comment, the problem isn't people in Solo/PG (or the game).
The problem is you don't like what you bought and are blaming others for your mistake.
