Churn and Burn
When retail investors trade stocks, the market impact of trading decisions are de minimis. However, when a fund trades its portfolio, it has a noticeable market impact.

DWS Tax Saving Fund
First, investors would have been better off buying a CNX Midcap index fund. Between 2006-06-01 and 2015-02-19, DWS TAX SAVING FUND has returned a cumulative 143.52% with an IRR of 10.74% vs. CNX Midcap’s cumulative return of 209.71% and an IRR of 13.83%. (http://svz.bz/1EHGTxu)

Second, the portfolio doesn’t look like a mad scramble like the one above. Markedly fewer holdings for longer:
When you compare the two funds with each other, you can see who is doing a better job (http://svz.bz/1EHJCa2):
Conclusion
Beware of funds that churn their portfolios frequently. It might be a reflection of shoddy research, poor conviction or immaturity that you end up paying for.
