Why can Adaptive Helm give more MR than a DClaw?

For reference, DClaw gives 55 MR, while Adaptive gives 60 (in the front 2 rows).

A good amount of item design went into what you expect to get out of it. If you want a lot of AD, slam two swords for a Deathblade. If you want a lot of attack speed, slam two bows for a Red Buff. Et cetera. But if you want a lot of MR, your best option for that is not to slam two cloaks, but a cloak and a tear.

I get DClaw gives other multiplicative bonuses, with % max HP and % healing, but I think the main focus of DClaw should be in the MR, with less emphasis given to the secondary benefits. It kinda goes against existing design philosophy. With Mystic/Ironclad combined into Sentinel these days, I think I enjoyed the game more when specific counters were strong. With DClaw's current state, it (and Bramble Vest) feels more like a generic tank item than the specific counter that I think it should be.
