Necro bump. I just found out about this game and started playing it over the weekend. I'm on Gunma server if anyone's playing.
I'm liking the game so far . . . well any game that features high jump is a huge plus for me. I just enjoy how it looks.
Classes are a bit unique as it does not adhere to the holy trinity. Utilizing and countering block/evade/parry skills are also something I don't see that often in MMOs. I tried a Blade Master and I could go from killing a solo boss with <30% hp left to >90% hp left depending on how much I pay attention to parrying. I should also point out that pots are expensive as heck for beginners and natural out-of-combat hp regen is something you'll only find in RO these days; aka not a source of hp recovery. Summoner, which is my main, on the other hand is just OP with an AoE life steal spell and that I have used zero pots so far going to lvl 28.
As for PvP, I haven't done any structured PvP, but I just have to comment on world PK. The most interesting thing as I haven't seen a system like this in other MMOs: you turn your PK flag on/off by putting on your faction's costume. Don't want to be ganked by the opposing faction while you grind? Simply take off the costume. Although, there is a 5 second casting time to remove your costume to prevent players from simply taking it off in the middle of a fight. Other than PKing for fun, I do believe there are quests that require you to put on your faction costume so those quests still have an element of PK ganking.
Game play aside, there are two little problems. Queue and spam bots.
Queue was horrendous at first. My first time took me 5 hours while my friend took 18 hours. But now with the added new servers which we moved to, it's not so bad. The longest I've had to queue on Gunma is 10 minutes and that's during peak hours. The higher pop servers still have ~1 hour queue times on peak hours.
As for spam bots. The dumbest thing in a f2p mmo: they have a 50 player block limit. In less than 10 minutes, I already blocked 50 spam bots in my chat, with lots more spam going on. Needless to say, until that is resolved, region chat, lfg chat, and faction chat are all dead useless. Faction chat is most important since up until yesterday, it was actually fun to chat with other people. Asking questions about the game, telling your faction where PK spawn campers are, those kind of things. Now it's all spam ♥♥♥ (I guess it took the spam bots a week to figure out how to get into faction chat).
Overall, an okay MMO for f2p. I'm not sure if it's something I'll ever play seriously in the long run, but it is something to keep me busy at the moment.
