Some thoughts on the cheevos:
40: Definitely the easiest set, as it turns out. Cazic was the only semi-tough one. Good choices, but might as well have thrown Inny in there too.
50: Nothing too serious here, Gorenaire and Yelinak are the main challenges. Seemed doable for a bunch of guilds.
55: Significant step up in difficulty from the others. Sol Ro seems like the big challenge here, but it might turn out that CBQ is. Haven't tried either yet (or the other two), we'll see. LDON and Emp won't be much of a problem thanks to VT gear being available.
60: RSS bosses probably won't be too bad. I'm curious as to how much of Anguish can be taken down at 60, if anything. Hanvar? Vishimtar is mechanic-heavy so it should be doable if people execute. Don't remember Deathknell 1, but at least it's the first event. Prolly would have made that cheevo for the Theater of Blood bosses instead. Lastly, Sendaii is probably gonna be the roadblock in this tier. That one is going to suuuuuck. It's a fight tuned for Anguish-geared 70's, much less 60's in Time gear.
65: Unsure if this means Lethar 1 or Lethar 2, there's a huge difference between the two fights. If it's Lethar 2, that'lll be a tough time. At 65 it'll be substantially easier to farm 70 raid zones for gear, though, so at least the gear level will be much higher here than the previous tier. Solteris 1 probably won't be bad at all. I'm thinking Solteris events 1-5 will be doable at 65, not sure about the last two.
70: This tier only has one cheevo and it's a doozy. Meldrath is a bad-ass in-era at 80 and geared-up. The one way I can see Meldrath not being a total monster on this server is if Crystallos isn't locked for some reason. The majority of Crystallos bosses are easier than Meldrath (Earth 1, Earth 2, Ice 1, Wind 1, Fire 1, maybe Fire 2 with good burst DPS) and the four non-dragon bosses could be farmed for gear on lockout. If Crystallos is locked, then it's gonna be all about farming Solteris as much as humanly possible I guess. I could see a lot of people skipping this one, especially considering the reward for this cheevo appears to be a teleport to Meldrath's Mansion which is a super odd reward.
75: Pallorax is an easy fight. Fippy is the very first boss of Underfoot, and a total beast regardless. Still, both of these should be doable without a ton of fuss, provided the server doesn't fall apart on the 70 tier if no one can beat Meldrath.
80: Cazic is one of House of Thule's toughest fights. I could see this being another Sendaii or Sol Ro situation where it's a process. I do think it's doable though. House of Thule will have a bunch of easier raids to farm so gear will be less of an issue.
85: This is a VOA raid, tier 2 I think (out of 4 IIRC) but I remember it being a beast of a raid in-era. So again we're not getting a layup here at all.
90: And then on the flipside, 90 gives us the easiest ROF raid and a tier-1 COTF raid (not quite the easiest but low on the list). These won't be any real issue if anyone actually gets to this point.
