I'd recommend reading a book by Larry Swedroe before you give up on Dimensional Fund Advisor (DFA) funds. I can't invest in them, but for the right fee I'd consider it. There might be other DFA advisors who charge less than 1%, so that's something to investigate.
I personally own Vanguard, but my understanding is that DFA emphesizes small cap stocks and value stocks moreso than similar named Vanguard funds. Take a look at morningstar's "portfolio" tab for "Vanguard Small Cap Value" and the equivalent DFA fund to see what I mean.
Most people who say 60/40 global portfolio probably mean:
40% US Total Stock Market index
20% Total International index
40% Total Bond index
And at least according to portfolio visualizer, that earned -0.64% in 2015. If you're questioning your allocation over a small drop, an advisor might be a real value for you. If they keep you invested when you want to sell and own more bonds, they could add to your returns. But if you can stomach tough market volatility you might think about lower fees. I suppose it comes down to what triggered you the last time you sold mutual funds.
