- Permafrost turned from 30% on autoattacks to 15% on all attacks. You'll be taking this talent anyways since frost DK sustain is pretty crappy without it and with it it's somewhat passable. We pay a talent to obtain what warlocks have baseline and can enhance further.
- Wraith Walk for all DK's extended to 5 seconds and made a 100% sprint. Reactivate again to return to starting point, can make for a juking niche in pvp.
- Icebound Fortitude made 1 min cd, or a 2 min cd with 40% mitigation.
-Death Strike cost reduced to 20 runic power. Increase damage relative to frost strike so it isn't such a massive loss of DPS for frost.
- Howling Blast with and without Rime proc boosted. It does way too little damage for being a proc when a DH just farts out eye beam and blade dance and mobs disintegrate.
- Cosmetically, Glacial Advance needs to go back to being icy bone spikes, current animation is ugly as sin.
- Runeforges, such as Razor Ice, should be available as illusion transmogs for DK's. Just like shamans and rogues have their versions right now.
TL;DR Low mobility class needs to be survivable and hit hard when it does connect. Currently it's simply lacking on both fronts. It hits no harder than, say, a demonhunter/rogue/monk for all its mobility, and it certainly isn't survivable compared to those three, even by Demonhunter standards.
