A few days have passed, and with yesterday as fresh experience where we ended up locking 5 zones, I guess I'll give what will probably be my last feedback for the current RvR system:
(De)Ranking of Keeps: The whole mechanic with Keep-ranks doesn't seem very impactful. The rank of the enemy keep is more of less meaningless, in the sense that you can't really de-rank the keep by other means than going for a full-on attack at the door. I'm wondering if it's too hard to de-rank the enemy, without attacking it directly. Also, even if the enemy keep is rank 5, it's still not much stronger than a rank 0 keep. Or at least it doesn't feel like it. So, what this basically boils down to, is that the ranks pretty much only matters the attackers, by how many cannons they can bring to the siege.
BO Timers: The timers seem very short. It's often just a chase from one BO, directly to the next, with almost no time to even fight at them. By the time you cap a BO, another one is already burning, at the other end of the zone - "Time to saddle up again, I guess". Could the timers possibly be increased? It can very easily become a stalemate, where the factions are ultimately just switching which two BOs they are controlling over and over, with no progress at all. It basically just becomes a game of cat and mouse. Not very exciting, or progressive. It's especially apparent in zones like BC or KV, where the distance between the BOs is quite long, compared to other zones.
Siege equipment bug out: Sometimes when you click a cannon or ram, they just kinda de-activate themselves. As in, you're unable to interact with them anymore. When this happens, they usually fall through the floor (If they are higher up). This is especially crippling when it happens to (one of) the ram(s), or when you have a low rank keep, and only a very low number of cannons.
Rams are way too tough: Well, before the problem was that the ram died too fast - Well, now it's the opposite

The ram is really tough. Like, really,
really tough. You can take a rank 5 keep with a single ram, and if you're doing really bad, it might drop below 75% HP. I think you could probably double, or possibly even triple, the amount of damage it takes, and it would still be really tough. Most keeps we have taken, the ram never dropped below 90% HP. Some keeps it still had 99% or 98% Hp when the inner went down.
Crashes at keeps: Being known as "Crashid" in Kings Own, I'm no stranger to this, or even new to it. I know this has been around for a long time (Since T3 at least), and that you don't exactly know what causes it (Corrupt packages or something, right?), but I still have to point it out. It's so disheartening to spend 4 hours trying to cap a zone, only to crash twice with 2 mins, when taking the keep, only to find out that I didn't get any influence at all and only 50% of the renown of everyone else (12k Renown, instead of 25k - Only got from the zone, but not the keep itself, I think. Might have been the other way around).
Ram spawn timers: This is pretty minor, but we found a few times that we ranked our keep up to rank 1, and then couldn't spawn the ram right away, had to wait for at least 5 mins. And since we didn't really have to worry about enemies taking the BOs (They hardly even matter after rank 1 has been achieved, we found out), we didn't really have to defend anything. We would just rush the keep and take the zone. Is that 5 min delay intended? And if so, what is it's purpose?
BO's impact: And last, but not least, are the BOs themselves - They are the highest priority, when your keep is rank 0, or your keep is under attack. But if you are have a rank 1-5 keep and it's not under attack? Then the BOs are completely pointless. They have no purpose. They are essentially just a distraction, or something for the pugs to chase, for free renown.
1) Resources - Rank your Keep to 1; and
2) Get siege equipment at your keep; and
3) Take the keep.
That's pretty much how the system works now. Any alteration from this sequence is just a chase for good fights, or an attempt to get a bigger tick, from the zone lock.
