Re: Your probem is not my emergency
There are two options, really
1) run. Run away quickly. Assuming you don't accidentally get a job somewhere with worse problems, it helps you *and* sends a message to the bean counters that there are costs beyond the old team's salary.
2) befriend the new guys and help them learn as much as you can. I can't promise it'll work, but in my experience it certainly seemed to make a difference to the underpaid, undersupported outsourced team to have *some* friendly faces who don't rage when things break, and respond well to clarifying questions about issues.
