Raid Tiers thoughts?

I've noticed an increasing number of raids where I go in with ~150k kit in normal and am matched against players with kits 5-10 times more expensive. I was in a normal farm recently where I was taken out by a full tier 6 with an H416 running M993. It's great when we can get a kill on someone like that but I'm not killing them frequently enough to cover my losses. What are your thoughts on kit brackets? Instead of putting up a bunch of 100k kits vs 500k or 200k vs 1mil, it might be more balanced to match people in brackets like 0-250k, 250k-500k, 500k-1m etc.
