Lag is reduced immensely.
I don't know where the servers are located - I don't know if the game has bad netcode, or if this is just the way the game is, but...
Hit detection is extremely poor. You are at a huge disadvantage with melee weapons because there's a delay time before you even know if your attack connected (meanwhile you're expected to dodge and guard). And due to lag, a lot of melee attacks will result in a hit exchange where you must take damage.
(Note: I'm an east coast USA user with a 100Mbps connection and a gaming PC.) Ok, so that's the main critical thing. Here are my other suggestions.
I feel like the core of the game is solid, but... needs way more options, such as the following graphic options: option to turn off bloom, thick outline for character models (would complement the comic book style), anti-aliasing...
Map design is pretty atrocious and hard to understand at times. Dungeon maps need to be revamped entirely to be more clear and they should also label your start point.
One key press of the W, A, S, D keys should move you about half the space it does now, so it feels more fluid.
There needs to be a menu for setting hotkeys wherever you want.
When using Tab to lock on, you should strafe towards/away from the enemy (right now you just move normally while locked on...)
Weapon switching is clunky. Pressing the F key to open my weapon selections is fine, but I find that needing to hover my mouse in the direction of the weapon I want to be very uncomfortable especially during combat.
More tooltips everywhere to explain stuff. There's like none... when you hover over a stat or something you should get a clear explanation.
Pow, Vit, Wis, Mnd, Dex should all be capitalized (POW, VIT, WIS, MND, DEX).
Need a tutorial on how skills work, skill leveling, skills on items, etc.
Pressing "M" should not also bring up your main menu, making you press ESC twice to exit out of viewing your map.
Last thing Your advertising sucks. If you just post a big boobed anime girl, nobody is gonna know what the heck your game is about. You need to include weapons and cool stuff too. Let people know what kind of game it is. Honestly from your front page portal this could even be an anime or a hentai game. There isn't a single monster or weapon in sight.
By the way, sorry if it seems like bashing. It's a pretty neat game (it basically seems like PSO2 with an open world between dungeons). This honestly feels like an alpha build of a solid game. I'm really surprised that you're releasing it officially on July 1. I don't feel that it's ready for release.
