Not a terribly huge change on Phoenix (and I've been here since the beginning). More RMT/merc shouts. Started seeing shouts from merc buyers from time to time, which weren't really there before.
More bazaars, better stocked AH - but the market does markety *** - some prices raise, some lower, some stay the same. Saw HPB get up to 900k/stack, which I found wild. Things like emp ws coins and relic forgotten things and dyna shards/voids are way cheaper. Cost of dyna crafted weapons has stayed relatively the same despite more shields. Cost of hoxne stuff about the same. Edit: Oboro/Paparoon bazaars are about the same, both in quantity and price.
Ambu waits aren't any longer, but about 10% of the time I'll need to wait to enter ein or a bcnm. 2/3 of sov behe pops were in use when I went to vanabout it, that used to be pretty rare.
Limbus has seen a bunch of race changes, which is a bit jarring. Have heard from a handful of folks who'd taken decade-long breaks come back and been enjoying it. Assist channels see more use.
Any given time we're at 1300-1700 chars online, where before we'd be lucky to push 900. A LOT of people are multi-boxing and that doesn't seem to have caused any major probs.
