We are both mmo-veterans, been playing mmo's for ~5-6 yrs. Mainly Ragnarok Online, Anarchy Online, and EQ2 (EQ2 is the one we are currently playing). We have tried roughly 20 different mmos. L2 is by far the most beautiful, which is why I am grasping to find hope for it lol.
Since you say you played AO I'll give you some similairities / differences so you will understand what L2 is more quickly:
- L2 has a much younger playerbase then AO. While AO seemed to be 20+ This one has a lot less mature base. You will notice this a lot with PvP actions and political drama (more hotheads, flaming, childish behaviour, e-thug attitudes)
- L2 doesn't have the huge European-scandinavian clientbase like AO. Not sure what country you are from, but this means a lot fun stuff happens after 3 am Euro time
- Compare Broken Shores / heckler SK grind missions at lvl 190-220 with the grind here
- Healers in this game do not have great PvP abilities like doctors in AO, while nukers are the same more or less
- Healers do not get the appreciation as in AO; L2 seems to appreciate DPS more, and tend to value it more then the healer
- lvl 210 seems to correspond with lvl 65 in this game in terms of time spent. lvl 219>220 somewhere in the 70's (below 76).
- No bi-weekly updates after playerfeedback, NC HQ is korean, not american/euro.
- PvP rules are the same as AO-Shadowlands in regards of flagging, with an added playerkilling / wars
- Base wars = Sieges, though castles are much cooler to defend and gives you more of an advantage
- Money is more an issue in this game; whereas in Ao you didn't need after a certain lvl (just raid), AO is more econemy based
- Quests in L2 are "kill x mobs to get x items" generally, not that AO had good quests though.
- Much less diversity in weapons due to skills being the same for the same classes, more equipement/moneybased
- Better pvp in L2 if you don't mind XP loss and griefing. L2 does not have "save your XP" terminals like AO has.
- L2 has uh professional people hitting the same mob 24/7 to get uh income (forum rules are blocking me here)
High-end content is a lot better then lowend. Busy places start at lvl 60 or so here. Sadly some classes are overpowered (nukers mainly) and played heavely.
Quests isn't the main thing in L2. Ppl only do them for the extra money during the grind, the XP awards are not worth mentionning. L2 is pvp, raidbosses and grinding in a spot, like SK farming in Shadowlands.
