Hextech Sweeper and Armor? Why not MR?

This issue was first posted to the PBE community, then to the NA Item Discussion Forum... Really hope that I can get some feedback here...

now grants armor and mana instead of AP. What is the reason for the change?

Patch 4.6 notes said:

The recent update to Twin Shadows made for a lot of design overlap with Hextech Sweeper, so we're pushing Hextech Sweeper into more of a tanky mine-sweeping direction.

But that does not explain why armor is chosen. Players usually need this item when the enemy team has or . The traps of Teemo and Shaco deal magic damage. I think magic resist is the more suitable stat for this item, and it upholds the spirit of the item by offering defence to its user. Armor is simply irrelevant.

Therefore, I propose that the build path of Hextech Sweeper to be changed to: + + + 300g = 2300g

And the stats will be:

• +250 Health
• +25 Magic Resist
• +10 Mana Regeneration
• +20% Cooldown Reduction

Because of the build path change, this build, compared to the one on live, grants mana regeneration instead of mana.
