The MAGE UPDATE and MR ITEMS
I see that in addition to core mage items changing, the magic resist items for tanks will receive alterations as well.
All two of them
Perhaps it's not within the scope of this update since the items belong to another class, but I feel that the counter items to the class being updated deserve some attention.
Right now tanks have a whopping one magic resist
item to default to, with
sometimes being a good choice when there's a lot of aoe or just too much ap on the enemy team in general or if you're just too poor to get the actually good item. The magic resist item you choose though should be based either on synergy with the champion, or the type of damage you are trying to mitigate.
For example, let's say you are fighting a
in one game and
in another. Against Swain, spirit visage is ideal since it gives lot of regen which slowly fights off dot damage. On the other hand, an item that gives sheer MR and possibly a first hit damage sponge would help counter le blanc's burst damage.
Or say you are playing either
or
. On mundo spirit visage clearly synergizes since he relies so heavily on healing, while Shyvana would prefer an MR item that emitted a 300 unit slow field every few seconds.
Now if we were fighting AD champs, I can go
if my champ can stick to people,
when there are two or more sources of crit damage,
to protect allies from attack speed,
for catching priority targets, and the list goes on.
TLDR; Mage counter building is shallow and has nothing to do with the enemy or the user MR items don't need to be stronger, just more diverse
