I finished up NG++. Probably wouldn’t recommend it to anyone else, though. It was neat to see the alternate paths, but they weren’t all that different, and although the last few missions (level 65 characters vs. level 90 missions) got challenging again, there was a definite lull of fairly easy and rote stuff, especially since there’s no way to do side missions more than a few levels above you.
The item and level scaling doesn’t really work well at these higher levels either – after a certain point, more skill points are a waste, and there aren’t any new item abilities that unlock. And the actual defense value on armor and shields becomes totally pointless – when the enemies are hitting for 700 damage, it doesn’t much matter whether you are blocking 30 or 50 points of it. The game is very much at its best from level 5-25 or so.
MVP was definitely my soldier, followed closely by smuggler. By the end I had my soldier pumping out 10-20K damage every single tick while covering the screen with a carpet of bombs to finish the final target off with a 300K burst. And traps are just amazing at keeping everyone alive. Void psyker continued being great for thinning out big groups, and force psyker mitigated a ton of damage and debuffs.
