wow dude, you didn't read what I quoted did you? Xsyon explicitly stated that tribe switches/toggles were never planned. If you read what he said, It is actually long-sighted for tribes near the lake to have protection, as a baseline, pretty much the aim of prelude. You could compare that to High sec space in eve. In my view it seems that expansions outward will be more dangerous and (probably) more valuable, which is attractive to both pvp'rs and 'carebears'.
I also completely agree, the alignment system should be meaningful. And from what I know it is planned to be. Stand back and look at xsyon, and appreciate the logic
