I'd like to see them admitting they have no clue about what is causing lag, and are actually hiring someone competent to properly investigate it - instead of randomly picking systems to nerf in the vain hope it might have an effect.
Because clearly 64-bit is not the fix, nerfing repeater RoF is not the fix, anything else they have previously tried is not the fix.
The problem is infrastructure, and most probably due to trying to run a system designed in the early 2000's on virtual servers with network attached storage.
