Is MT5 already good for making and testing multiple-pairs EAs?

[Tosh5457]

Hi, I've been using MT4, but after understanding how diversification can improve results I turned to MT5, so I could test EAs on multiple pairs at the same time. But I don't know if it's still on beta, and if the strategy tester is reliable. I saw some topics complaining about the strategy tester some time ago, so I'd just like to know if MT5 is good enough to be trusted and to use? Thanks :)
