While I agree with most of the things what you've said, I cannot agree on that Apathy is over-rated. Apathy is clearly the stronger side if allies and sister tribes are taken away. Why? Because Apathy works together to gain ground and, well Corp, Corp is just internalling on a major scale. No, I'm not taking shots at Corp, but those are just statistics. Right now, Corp is internalling Zain - yes, well placed villages etc, but idk, stats show alot more internalling previously to that. Which means either the players are inactive or just quit, merged accounts too maybe, but haven't seen much of internalling from Apathy. I'm not saying internalling is bad, but if you're in a war regime and you haven't been doing anything for the past week or so, it shows incapabilities in the leadership. For both tribes. When this war kicked off, I excpected it to be huge, but what did we get? Pretty boring encounters on the core - like you said - it's been a stalemate.
Back to the topic on why I think Apathy will be much longer in W91 than Corp will, Apathy has their backyard pretty well covered. There's TRK and then there's REP. Yes, both tribes have been growing substantially over the past few months, but nothing that big that would actually threaten Apathy. Apathy probably has pacts with both of these tribes, either alliances or NAPs - either way, good for them. So that leaves us with two possible frontlines. BeCool and Corp. Two. Let's take Corp for instance. 3 possible frontlines that involve Apathy, Rimjob and BeCool - all of the major tribes in W91. If these three decide to wipe out Corp, then Corp gets wiped out. Corp can't hold its own against three major tribes, let's face it. I'm not ranting about Corp, I know a couple of players there who are nice people, but I think the time when Corp officially leaves this world is bound to come. If they don't magically get an alliance with Apathy and decide to hug this world out, which I know for a fact, Jasper won't let happen.
