My question is, how big is Cyrodiil? If it is the only zone PvP is in, it better be pretty big or it will get old very quickly. We have already seen this exact same thing fail in GW2, where there are only two maps, one of them has always svcked horribly and the main one is so small that it got old for most guilds in a few months.
If there aren't enough variables in the battles and the zone isn't large enough, this one-zone 'world pvp' is going to get old pretty quick, and all of the PvP guilds moving to ESO will once again be looking for a new game. I'm really worried about how long the PvP is going to last with one map.
