There is a difference between adapting to a change in mechanics or adapting to a difficult challenge then adapting to an arbitrary cost whose increase provides no increase in difficulty only increase in overhead.
For example if there were now a tax each time you started an operation of 300k credits you bet everyone would be in arms about it and rightfully so. Doesn't mean I won't just pay it and move on with my life, but it is just a bad design decision.
Fairly ridiculous example, and you do say you'd just adapt to it.
I honestly just don't see why this is such a big deal, there are plenty of ways to get money to cover the repair costs, whether it be dailies, crafting, or selling resources, or more. People didn't really need to do these before because often the runs would cover any costs.
The casuals seem to be the one ************ the most about this, which, to me, seems like it should be hurting them the least.
