sejuani gets 5 armor and a 1 second increase on her weakest move
 

"better dust off sejuani guys shes ready to be out on the rift!"

You're right, they should have nerfed her instead, that would have helped her more

Base armour is not to be sneezed at when tackling the jungle.

All this talk of Sejuani, you'd think that the Rammus fans have fallen into a coma or something.

Her W is weak? It's like amumu tears only it does more damage to squishies due to scaling off of her HP instead of theirs, and having better scaling as long as they are frost/permafrosted.

Something is better than nothing.

Except ammumu's is on all the time.

Bad comparison.

So is hers with max CDR now

If you think her W is her weakest move, you're not too familiar with Sejuani. Her Q is far worse than her W could ever be. Its only use is a dash.

6 second ability on what like 9 second cd? hers is up often as well.
