Just by chance I found this in AW. I"m assuming this applies to PVP in general on all platforms.

We have been working with the Combat\Classes team for improving Cyrodiil performance while they are also constantly adjusting\analyzing items, abilities and builds. The PVP crew is hard at work on Imperial City while brewing other ideas for Campaigns to give them a different feel and addressing long standing issues like population concerns with the meta-campaign issues of alliance dominance. Obviously there's still more to do for Cyrodiil and PVP as a whole, and both the PVP and Combat\Classes teams are reading the forums and relaying these posts to each other while discussing options. Some of these options are getting more solid and will be up for discussion soon!
