the developer should make a list of enemies that are available and ones that are not. would help alot. (example) you are looking to kill bearserker, cant find it. just look at it and you can just easily go to the available server quickly. also the same for veins.
There should be Auto Loot button so you can loot quick because sometimes when you loot you don't get it because the enemy disappeared when you were gonna loot it like if you killed frocto and waited,then it would disappeared and you would of had a chance to get frocto scroll
