Make frost staves useful again

Since they reworked many weapon passives already in this update, why not do the same thing for frost staves? I'm really excited about the 2h and dw changes, which will probably give us more freedom to choose between the individual weapon types. It's a shame that they didn't use this opportunity to make ice staves more useful again.
Now I really don't understand why ZOS are so hellbent on turning frost staves into a tanking weapon. Frost staves have never been tanking weapons in TES lore and it makes sense that way - how is a stick going to reduce incoming damage???
But since they insist on turning frost staves into a poor man's 1hs, they should at least add a bonus to keep frost staves relevant as a dps option.

Instead of applying minor brittle to enemies when chilling them with a frost staves, why not add a flat 10-12% crit damage increase to frost staves instead? Or how about adding a dot/direct damage bonus to frost staves, or a flat 6% damage increase to all sources. You could even have frost staves grant spell dmg or spell penetration like maces and swords.

What are your thoughts on this? Would you like frost staves to become a viable dps option again, and how would you do it?
