So here we go!
Anti-cheat. XIGNCODE is by far one of the worsts anti-cheats ever made, same as the AhnLab HackShield. Actually the one that works out very well is BattlEye, it does not keep the game completely out of hacking hands but at least much, much more than XIGNCODE. BattlEye team also bullfights with hacking websites.
Parties. If you want to find a game in party with colleagues/friends is because you all want to be on the same team. Right now it puts the whole party on the same game, but not on the same team. I don't know if it's a bug of if it's intended to be like that, but anyhow, parties should be placed at the same team.
Hit registration. Kinda weird and random sometimes. I don't know if it's because of the actual server issues (like micro-cuts, drops, etc.) or it's intended to be like that.
Server issues. As mentioned at the above point, it kinda drops or there are micro-cuts. It cannot be in any way my Internet connection as I'm from Spain, got 300Mbits D/U and having 5-ping bars on each game. There are also players that cannot even see the lobby background, which seems to be server-sided.
UI. Kinda laggy sometimes. Maybe it's because of the same thing as the hit registration (server issues). Who knows. Sometimes you have to press like 5 times to equip/wear something. It's truly annoying.
All the item descriptions should have something similar to the weapon attachments, like "+X damage resistance" or "+X movement speed" if the items really grant these buffs, as I'm not aware if depending on the armor you wear, your resistance is harder/weaker or you move faster/slower. However, if the items are only cosmetics forget about this point.
For the rest this is an amazing game! Hope to see it in competitions very soon.
