Tying to make a build with Grizzly Rage? You can’t reduce the cooldown until GR has ended, so half of the time your build doesn’t work.
A poison build? The posion support is weirdly spread across bear and wolf, so you can never take them all.
Any Earth build? You’re forced into Overpower + Vasily + Ursine, since that’s by far the best and our “the best” is needed for T4.
I tried making a Gathlen’s build with Stoneburst, NF and Banished Lord’s, but it’s just an inferior version of the standard Vasily + Ursine build.
