Anyone know the chances of getting a rank 1 or rank 2 rune with Earthforce?

Comparing to Impenetrable (which only has rank 1 and rank 2 for the disc), the chances of getting a rank 1 to rank 3 are 40/30/30 and 30/40/30 respectively.

I am unable to find similar data for Earthforce rank 1 - 3, except that it cannot proc a rank 3 rune ever: ?/?/0.

We know that, assuming you have AA and impen focus, Earthforce and Impen are the same regarding duration, reuse, defensive (90%). Earthforce has a slightly lower upkeep, but is negligible. Earthforce has the dps bonus (how much?).

That said, what do you guys use? And for what situation? In a group or solo setting, I'm guessing Earthforce is more valuable. You can survive a few hits and you get the dps boost. In a raid setting, when you catch aggro between switching tanks, I'm not as sure. Do you take the chance on getting a rank 3 rune over the dps boost (which is all it comes down to in any situation). Rank 3 provides 2 more hits over Rank 2.

Now, from a rune only perspective, Earthforce rank 3 -could- be just as good as Impen rank 2 if the rank 2 chance is 100%.

Impen rk2 average for 100 uses: (30*3 + 40*5 + 30*7)/100 = 5.

If Earthforce has 0/100/0 the average for 100 uses: (0*3 + 100*5 + 30*0)/100 = 5.


So once we know these numbers, we can then have a debate on whether impen has a place at all in our line up. Just curious, but figured would be an interesting talk. Thanks.

Some things to keep in mind:

With a T3 BP, you can use Earthforce 30% more often than Impenetrable (2min 6 sec vs. 3 min)

It is likely that any AA going forward will be for Earthforce.

Personally, without the T3 focus I went with Impenetrable. Now that I have the focus I use Earthforce.

60-70-80 chance of getting rk 2 rune, iirc

If I had t3 Bp I wouldn't use impen again.

Ahh I didn't realize the impen focus worked. I thought they made Earthforce inherently lower reuse without the need for a focus, so that they were the same reuse. Maybe it was only the AA duration that that was true for. A solid case for Earthforce once you have the focus, especially with rk3.

Anyone still leaning towards Impen once you have rk3 disc / t3 bp?

I won't when I have T3 BP. I was thinking with BP it would be under 2 minutes with the T3 aug, but someone posted on Alla's that the T3 aug does not stack with the BP reduction, so you can't get under 2 minute reuse. Still, 2 mins and a few seconds is sexy.
