Apparently iRO is going to release 3rd classes for Ymir server this week though and later on on Valk.
But you have to know that, they're running on Aegis and they don't have customs like stated in OP, and they are apparently also going to change some things on the renewal update just like RO in Japan did.
If you want 3rd classes in this server you'll have to wait for eA release.
Edit: And you won't like Renewal, your beloved drops will be cut out at lame percentages if you're too high leveled. 
email me the link? i wanna play

Wtf, no IC O________O
i'm pretty sure doppel does like 10% more aspd, i think dont know for sure. Played a few servers and dop gave 10% -,_,- so we'll need like quad dop daggers to 190 aspd, this would really mess up niff black smiths and a few other things. And alot of us cant live without IC

I really really don't want third classes x_x I guess I'm probably not gonna be around when that pops up though, so. Meh.
As long as we could keep our mechanics and keep IC I might want 3rd classes. We will come to that road later though.
but they're so ugly ): and I'm just totally not interested in having to learn a whole new set of mechanics u__u;
@roon, freeze yourself? and play in the future? Shadow Chaser is ugly, makes me want to throw up when i play my stalker with shadow chaser sprite, other than that the rest of the sprites look pretty cool, if you dont like them, alot of servers have customized third class sprite, and you can ask them if they could email you the sprite.
Its possible to remove or nerf broken skills.Many servers do not allowed 3rd class skills to work in pvp and war, while some skills have been nerfed down to suit with current stuff. Although, it wont be bad if we no longer have 190 ASPD or IC. Maybe we are spoiled by that. I still to date play in places where the max aspd I get is about 181 and Casting could be made ridiculously less but not instant.
And it always reminds me of the suffragium priest I had in my partry while I played Wizards in official servers.
It is lot of work but you can rewrite or edit mechanics to suit us.
That apart it would be nice if we had a beta server of aRO if they do need to test 3rd classes - Remember when Taekwons,Ninjas and slingers came out - we had a test server to test em out first. .

A lot of the skills are pretty badass. For example Rune Knights "Dragon Breath" skill. I played a high rate with highest level was 255 and skills did the exact thing it said on doddler website. RK would walk into a field full of mvps barely any room to take a step, uses Dragon Breath once and all mvps with less than 1m hp would fall. Dragon's fear we all know that one. Guillotine Cross makes EDP last for 90 secs, i <3 this one. Shuras "rising dragon" skill which allows 15 spirits, so 3x FO's which will hurt alot. Also I think it was Gate of Hell from Shura, a mid rate Shuras were dropping Satan morroc in less than 3 mins with all 3rd class buffs including gospel and a few others, also this server doesn't have mvp cards or overpowered gears like kaho or TG or anything like that yet Shuras raped Satan Morroc. Shadow chasers being able to use Strip accessory <3, prevent people from using pecos, humoculus, falcons for about 20 seconds sound really nice, i'm sure Lord knights with nib wont come near to Shadow chasers (Masquerade - Gloomy skill). Really fun skills, to bad it'll all be nerfed or changed by the time we get it due to SQI's and our customs

@Farnsworth - yea your right all of bugs and aRO might just crash one day and all the data might be erased, but Talis might have back up data when the change from aegis to eA.
my RK and GX got deleted

since the server crashed with a few bugs after the Sorcerer was implented and it ended up erasing all the data

on the other server
