I'm lvl 14 now, imo the missions seem to be the biggest issue. There are several missions where the "lvl" for the mission bears no resemblance to the mobs you will need to fight, there are some other missions which you pick up and are in an area that you havent yet unlocked but theres no mention of that and there are certain other missions which you simply shouldnt even be able to pick up yet but can - for example , Lost and Found , which I picked up at lvl 11 (says its a lvl 13 quest) , however turns out that the mobs I need to fight to get to the mission destination are lvl 18s, which promptly slaughtered me. Anyway, I respawned many times and kept battling through and eventually after an hour of repeated tries I managed to kill all the lvl 18s and get to the mission destination only to find that the NPC wasnt there. I figured the quest was glitched but nope, googling it revealed that you cant do that mission until you have done its pre-requisite mission "Foreign Code" , which I didnt even have , so clearly the game really shouldnt have let me pick up the 2nd mission in the mission chain if I hadnt yet done its prerequisite mission.
Luckily these issues are not major ones to fix I wouldnt think and at the end of the day I'm still having fun and for a debut title it has already got better graphics and aesthetics than many much more experienced studios can manage with their titles. I hope the title continues to be a success because I really think that with a success under their belt and increased budget for their next title this is a studio who could put out some very good titles.
