At 990 the Barrier colossus one taps me. There are ZERO effective weapon combinations to take his shield down AND do any significant damage before a single bullet from his slug spammer kills me. Every weapon with mods is CQC only. But, hey we KNEW the was gonna be the cluster-blam!- result. How the -blam!- did bungie think this would be acceptable?? Edit: The issue is not with any of the rooms prior to the boss. I cleared them, including the Champions wth only a couple of deaths. The issue is the boss encounter. There are no ammo drops. It is strictly a kinetic and energy weapon encounter- you will not have heavy thanks to ammo starvation. Anti barrier are smg and sidearm only. No impact, range, or sustaining damage ability. That is exactly why this forcing of "mod metas" is bullsh!t.
