Elsword, by far it's gotta be Elsword. I dumped more hours into this game than you guys can possibly believe.
It starts out cool and everything, with a decent enough premise and some characters, the problem is, once you actually start understanding the game, you learn how shitty it is. All of the game's PVE is ridiculously simple and repetitive, there's not even a real story to talk about, most of the game's ACTUAL story is given outside of the game itself, which is already a shitty enough decision, but between a bajillion rewriters, inconsistent information, outright contradictory information AND the fact that they simply decided that all character jobs and personalities are canon and yet not at the same time just makes the story completely stupid in the end. The most glaring fact of this is the "ElType" comics which were originally supposed to be extra story tidbits explaining the world and giving character backstories. They have devolved into "what if" fun fests which are entirely non-canon and serve only as a cash-grab for koreans.
Dungeon Difficulty?
What difficulty? Grab literally the highest-level content in the game possible and you'll see that it's ONLY difficulty comes from the fact that all boss attacks are inescapable, unstoppable, have little to no telegraphs AND deal a bajillion damage. And don't even get me started on the bugged bosses (Looking at you, Ran.) Or the bosses which were intentionally designed to be bullshit (I'M LOOKING AT YOU TARANVASH AND YOUR INSTA-TELEPORT-COUNTER BULLSHIT).
The fact that it's pay-to-win doesn't make it any better, good fucking luck trying to do any content post level 50 without a +8 weapon AT LEAST. I should probably mention that any weapon upgrade post +5 has
abysmal success chances and can also break your weapon, rendering it unusable unless you buy a specific item for real money. Oh, and by the way? There's an item that makes said abysmal rates slightly less abysmal, which also costs real money. And the chances are still fucking terrible.
The game emphasizes this stupidity so fucking much that having a +9 weapon is considered
average, so much so that the only way to challenge players anymore is to make "achievements" which, by the way, are absolutely fucking unreasonable. And when I say unreasonable I mean "Finish this dungeon in less than 4 minutnes! Oh, btw, the dungeon has 3 minutes worth of loading time and the boss goes invincible frequently and randomly, all of which count against your total. Good luck!" or even the all-well-known Reaper achievement, or "Do 7-6 800 times". Neither of which, by the way, are isolated achievements. Between the "defeat the raid bosses 1000 times" achievement (bosses which also fall into the "deals too much damage, can't escape, has too much health and little to no telegraph" pattern) the "killl 9999 angry syrapes" achievement (of which you can get at best 16 in a single specific dungeon run, and some runs you can literally only get 2) or even the "SOLO BOSS RUSH (a can of worms in and of itself I assure you) IN CHALLENGE MODE 1000 TIMES" a process which can take more than an hour per run.
And let's not even talk about the bugs, or the balance, or the hitboxes, or the netcode, or the literally everything else, seriously, I watched this game grow from its early beginnings and the only reason I stayed in it for as long as I did was because I had no alternatives + the friendships I had made due to them.
If you want a summary of EVERYTHING that's wrong with the game...
This 30-minute long video covers pretty much all of it. The fact that the uploader got enough footage for a 30-minute long video out of nothing besides videos which average on being less than 20 seconds long (and the fact that this isn't even all of his footage) should already tell you volumes about how shitty of a game Elsword really is.
