Landslide Enchant instead of Razorice for DW?

Landslide Enchant: Permanently enchant a weapon to sometimes increase attack power by 1000 for 12 sec when striking in melee.

I am not huge with math, so i have no idea how big of a dps increase Razorice is, but is there any chance that landslide could be a better option for DW Frost. So it would be MH Landslide, OH Fallen Crusader, or is Razorice much better than Landslide?
Where is landslide from? I've never seen it.
razorice is still better. Its a flat % increase on HB, FF ticks and FS .. thats not to be taken lightly.
Landslide's an incoming cata enchant.
I'm not going to bother doing any calculations but I'm going to say it's not worth it. If it happens to be better, RI will definitely outscale it. 1000 AP will never be more than 1000 AP.
I think generally a % number tends to scale better than a flat number, as people have said.

Of course, though, the graphics of our runeforge enchants are severely lacking.

The Landslide animation isn't very appealing either; at least not IMO.

Hurricane looks OK, but it's too bad the effect is only at the base of the weapon. Hurricane might actually be fairly useful for DKs too--450 haste for 12 seconds could potentially help with rune regen quite a bit.

Avalanche would look fine were it not for the snowflakes; the frost aura is cool though. This one might be fairly useful for DW DKs, but I dunno--probably loses some of its worth since we prefer slow/slow.

Power Torrent, IMO, is by far the best looking enchant in terms of graphic effect. Unfortunately it's completely useless to DKs.

In any case, our many Runeforges could certainly use a graphics update, if not also a mechanic redesign. Fallen Crusader is good, but the graphics suck. Razorice and Cinderglacier are decent for Frost specs, and the graphics aren't too shabby either. SSG graphics are terrible.

Lichbane graphics aren't bad, but the mechanics are completely useless. Nerubian Carapace graphics suck, and the mechanic is now obsolete. The other parry/disarm and spell reflect/silence ones aren't terrible mechanics, but in comparison to our other runeforges they just aren't up to par.

I'm disappointed there's really no runeforge (or two) made for Unholy spec like there are for Frost spec. I think DKs should definitely get some kind of +haste runeforge considering how haste now helps with rune regeneration. I also think we should get a runeforge like Razorice or Cinderglacier but made for Shadow damage for Unholy spec.

Given that ap is gone from gear and the scaling we will get on str to compensate, i wouldn't be complaining about RoFC. As for landslide, I doubt its uptime will make it anywhere close to our runeforges.
I wasn't complaining about FC's mechanic. I was complaining about the graphics of it. And the part you quoted wasn't even about FC.

Fallen Crusader is good, but the graphics suck.
