+7 success rate ? G.Ms help - what happens if we use enahnced core ?

[yummy]

I doubt this is accurate either. Going from +5 to +6 you need two cores to upgrade. I doubt the success rate with x2 Ech is only 30% People have gone from +6 - +7 (using Ech's) without a single fail.

this thread was posted before the update.. so we're replying to the old upgrade system lol
