Why the preference for over CL 10.0 for an instance capped at CL 10.0?
I need experienced players who have beaten EB before like my self not your run of the mill "Dur lets run through SS that's the only way to beat it" noob
I have heard of people getting to CL 12.0 without once beating the EB often coming straight from doing PS repeatedly then going to DMS. It's probably akin to high TCLs translating to actual experience. But, I do understand your point.
That does leave highly experienced SS/EB players who never played DMS out of your pool though.
