While it's combat is great and it sure did have a lot of potential as a game and is even actually enjoyable, it's not something I'd recommend playing in the long run. This is due to quite a few reasons, the combat is great and there was/is potential but the game has fell short in literally every other way and continues to do so with no signs and a incredibly small chance of ever being fixed.
I mean lets start off with a few things
-Lag is common
-PvP is not balanced and never will be most likely
-PvE is not balanced and never will be most likely
-New classes always eclipse previous ones and are broken in order to promote new characters and purchases of costumes and other things for these new characters. The community also supports this (Goes along with it IE: Bandwagonning,etc) and will not allow you to join parties if you're playing a class that isn't as good as some of the others sometimes.
-RNG is HUGE in this game and very good at screwing you over with it (Probably in part to get you to pay for items you need to safely enhance gear instead of investing large amounts of time in getting gold just to try again)
-Sub classes of each main class usually change from which one is best to again, promote buying class change scrolls and what not for money.
-The graphics are worse than something from 2005 and the game is not optimized at all or something is totally broken. Even with current hardware don't expect 60 fps, it's always been like this.
-A lot of the really nice purchasable things like mounts, wings, weapon skins and other things are only obtainable by dragon eggs. It's like a lottery with a really small chance to get them with each egg and they aren't cheap either. $1.50 for one $30 for 30 and you might not even get one of the good things you hoped for by spending that much either, there's people who pay hundreds to get certain items.
Now none of this is the main issue with this game, in fact these aren't even all the problems that just add onto what is the main problem. I'd say the main problem with this game is the roots of it. The way the game is designed, you have dungeons, nests and raids which you can do a certain amount of times a week. Dungeons are useful for leveling up till cap and dailies (Doing each set of dungeons every day to get a stamp+rewards). Nests are useful for getting drops towards crafting gear and other things. Raids are for end game gear, there's also a hardcore version.
So here's the deal, level caps come with
1) Filler content (Constant class rebalancing and fixes that never actually fix anything and just shift power for money)
2) A new set of dungeons
3) New nests and raid for each cap
4) A new class
You'll get one good update every 1~3months with others being nothing special
So.. here we go, you put so much effort and time into content which is not fun for more than a week at most in order to be able to be strong enough to enjoy the new good content that comes out every 1~3months and is fun for a week at most (Excluding raids). Dailies every single day, nests every week (that are boring once you've learned them which takes about a week because it's literally doing the same thing every time you do them over and over which goes for any content released in this game) and the same applies to raids after a bit too. You also grind dungeons for drops, maybe grind some other various things the game has for gold and that's.. it. The game itself is fun, the combat is good and all that but all you're doing in the game is the same thing over and over and over every day in order to gear up which takes time just so you can enjoy new content. There's nothing else to do, it's all instance based and not open world so you're doing this or afking.. It's just.. a shame, it's not worth your time. You'll have fun at first but by the end of it the boring, repetitive, and chore like content you need to do to get strong every day and week heavily outweighs the fun you'll have with new fresh content.
Again, this is only the main flaw, there's a million other problems to this game stacked on top of it that I haven't mentioned. There's better stuff out there to enjoy and Black Desert is coming too which has potential. If you're looking to play a game and enjoy your time in it and have fun (The reason most people play games in general), this isn't for you.
