Before the flood of new sectorals, most factions had access to profiles that fit every role (Camo Infitrating Specialist, Basic HI, TO sniper, MSV2). It was just a matter of some factions had more or better versions than others. It was rare for a faction to be missing a skill completely (HB & MSV2). With the flood, Sectorals are more focused with unique play styles, one way of doing that is to have some sectoral have complete gaps. We see a couple sectoral having more noticeable gaps (ex:DBS missing HI). IA has a lack of non-HI troops. At this point I don't think IA was supposed to get access to MA and have limited access to infitration, which is ok. But sectorals need to have a minimum number of profile to keep their interest. DBS has 19 profiles which is too limited (IA has 24). I think the the Hulang are a filler. Unfortunately IAs limited number of 'playable' profiles makes it hard to have diverse lists. Everyone who plays IA starts with the Zuyong core, But given the alternatives its hard to move away from it. I don't really see myself playing IA much past the different versions of the Zuyoyng core with Liu Xing and Zhenchas. The rest just aren't cost effective for what they do.
