30 seconds for axis and 20 seconds for allies is the default Enemy Territory spawn time. Having started ET in late 2006 I always considered myself a 'new schooler', but now I'm surprised that many people find 30 seconds spawns too long, maybe I'm an oldschooler after all
Before playing in FA servers I had never played in a server with less than 30 seconds spawn time (well, except purefrag). Even my old clan's jaymod server had 30-20 like all 'fun' servers I ever joined in the past. I think this trend of using short spawn times started with splatterladder rating, raters wanted to kill more players, and some servers lowered the spawn times, then all the rest copied...
For me, with long spawntimes you need more strategy to avoid being spawnkilled, and avoid getting always full spawns, so I think it's a more interesting game with more teamplay. And with short spawns a lot of things, like push out with low timer and then selfkill, make no sense at all.
Still some things need to be fixed (I can't still call arty, probably I need a certain amount of xp, so I never play fieldop) but I enjoyed playing in this server, playing for obj is hard when you are not used to it
