I keep reading somewhat concerning reports from people who have 'finished' DC. I use the term 'finished' because an alarming amount of them seemed to have used cheats to beat a particular section or boss. So far I've read about bloated hp, crit immunity, bleed/poison immunity, respawning mobs, trap immunity etc. My highest character (22) is a crossbow user and after reading another crossbow player's reports on the DC I just straight up rerolled because I realised the area seems to have too many hard counters to my build. Right now I'm playing an AR commando but I have a strong suspicion that I will hate myself for not having stealth. Not to mention ammo consumption which is off the charts.
So my question to people who have finished DC - what would you consider a good overall build for the area? Ie, which mechanics will get hit the targets. Is melee only viable or is ranged as backup absolutely necessary?
