TDB is going to stay 32 light capped. I can't say for sure they won't go to 34, but I haven't seen any indication that they will. That's why there are 331 weapons and the hive disrupter perks. They're pretty much locking the non-raiders out of the hard raid with that perk. Personally I think using level 33 enemies is a cheap way to artificially increase difficulty, the same goes for adding lots of lower level enemies. I hope they handle it better in HoW. But I doubt it. I dunno, time will tell.
