To use a D&D reference, whats the difference if I give myself +3 gear while everyone who plays legitimately has +1? We are all going to get to the same place eventually right?
Ok, so, I dm for a group of my friends every now and again, so I feel the need to point out just how asanine this comparison is.
Firstly, that's not a good analogy. This player didn't hack the game, they exploited it. There is a vast difference.
To translate this system over to DnD, you'd have to have it be a player exploiting something the dm has set up (not a game rule, as only the dm has power to "ban" people here), like, say, they created an enemy that respawns each day and always drops a high value item, and one player starts resting each time and repeating to farm that item.
In that situation, if a player started to exploit something I set up, the last fucking thing I would do is say that they could never play with us again. Instead, I would use the power I have over the game to alter it, change something that stopped them from exploiting my setting. I have the power to do that, so for me to kick someone out of the campaign instead of just altering would make me a huge dick. It would likely put a dampner over the whole campaign, honestly. I mean, who the hell wants a dm that gets mad and kicks you out over something like that? The whole group would probably be having less fun, as they're now having to walk on eggshells around me. And if people then stop coming to the sessions, then hey, I've killed that campaign. Good job me.
In this case, BioWare need to patch this. Reacting the way they have is just antagonising their playerbase for the mistakes that they themselves have made.
