8% is a great dividend for an ETF. Dividend based ETFs with "good" returns are hard to find so this is an awesome find on your part.
I am not super familiar with "midplay" gas and oil industries. The dividends seem pretty high so I wonder what drives that. I agree with you oil and gas won't be going any where any time soon.
I share your skepticism on investing in stocks with international exposure. For me the returns need to be higher to justify the risks.
