http://www.angrygamer.net/sodwiki/index ... e=Leveling Might give you some leveling ideas, but there are tons more options than what's in there.
I've had 65 toons for years, but I haven't played them in a long time. I'm getting back into raiding again and the encounters are awesome. Very well thought out and well done considering the technology/game engine they're using. Raid content is designed for 18 characters. Raids can't be larger than that. Currently there are about 9 "tiers" of raid content, and my guild is on tier 6 or 7 I think.
There are a few drawbacks to SoD. Because the server is reverse engineered, there are minor glitches and such. For example, every so often there's what people call a "pl bug," and what happens is you get constant packet loss and need to either camp out or /q and come back in. It usually happens once every hour and a half or so, but it doesn't slow things down much. Really, the biggest drawback will be your unfamiliarity with content/zone connections, but look on the bright side, you get to explore all over again! Some things are the same, sure... But a lot is different.
There's a lot of storyline to it too. It's really awesome when Kaezulians invade and take over zones. There's a worldwide emote announcing it, and you either defend the zone by killing all the invaders in X amount of time, or the zone is taken by them. If the zone is taken, the adjacent zones get invaded. They can even take over big cities and such until people band together and fight them off. You need to clear them all out of a taken zone for the zone to be liberated and go back to normal. There's also some pretty decent raid loot from it.
I'm trying to think of what else I can say about it. All the classes are more or less the same as in original EQ, but there are some twists. For example, Wizards can get critical blasts at level 1 (2x damage), and with AA's, they can get ultimate blasts (4x damage) and very rarely, primal blasts (8x damage). Primals can hit like, 25,000 dmg+, but trust me they are rare. Likewise, clerics get the chance to critical heal at level 1.
There aren't really disciplines in SoD. Instead, there are battle stances. Every class gets normal, aggressive, and defensive battle stances. Warriors and other melee classes get class specific ones. For example, my warrior has a vindicator's stance that enhances mitigation. He also has a stance that increases avoidance that only small races get (he's a Dwarf). Stances for aggro, even a fun little "final stand" stance that reduces all melee damage taken to 1 and decreases my hit points to 1 on exhaustion (it drains your stamina fast). If you play a melee, type "/s list" in game and it'll show you a list of stances, what they do, and what levels you can begin using them.
GM's also throw together little silly events occasionally too, and sometimes big not-so-silly ones. One of the silly ones was a level 1 gnome race across Eastern and Western Plaguelands (E and W commonlands, in SoD populated by level 45+ kos mobs). The winner of that won the title "the Swift" for their main character. I got third place and won a Teddy Bear with a right clicky "Hug" effect. Woot?
