CoolKnightST1 votesI don't believe you understand the title correctly. The topic was never reffering that whe don't have supportive MR item. Whe actualy have plenty of them:
that build into (HP/MR/CDR) and 
(HP/MR/AP/CDR) [new buildline on pbe]
as HP/AP item
that build into 
(MR/Mreg/CDR) and 
(MR/Mreg/AP/CDR)You can't compair an MR/HP/CDR item with an MR/AP/CDR oriënted item.
So far whe will get 3 supportive mr aura items (2 to increase it & 1 to reduce it). While on the other side of the picture whe have . These options are verry limited for supports.
An example: Let's say you play a poke support. Their are a fell available builds for this depending what champion and and situation (boots & sightstone not include):
)
)
)
Let's say you play 
support:
..Both build cases are really extreem for a poke support. You rather build full agro or just build something passive entirely. Their is something in between that's but that item was never design for a poke support anyway.
That's why their is room for an MR/AP/CDR item for these kind of builds.
EndlessSorcerer1 votesWell, before the trinkets came out, I would say that Riot didn't want to put summoner spells on items. As it is, this isn't a bad item. It doesn't have an obscene stat efficiency, it gives stats useful for supports, and it has a strong active. I could easily see this being picked up against assassins, similar to Mikael's Crucible against CC or Locket of the Iron Solari against AoE magic damage.
CoolKnightST1 votesWell that's the whole point about it. A singe target offensive support item.
Sailor Mint1 votesWell that's the whole point about it. A singe target offensive support item.
That's what Frost Queen's Claim is for. Pick one, damage/CC or tank stats.
