So is it just me, or do other people find that it's 50x easier to play Frost as DW than it is as 2H, as to maximise 2H DPS, you need to make sure you spend those KM procs on Obliterate, whereas DW spends them on Frost Strike, yet it's ridiculously easier to keep enough RP ready to dump into a KM Frost Strike than it is a KM Obliterate.
Similarly, it's easier for DW to dump Frost runes into Soul Reaper as it's less important to make sure you've got a pair of runes ready for Obliterates.
And finally, it's easier for DW to hold up resources just before a Pillar, as you can bank 75+ RP and get ready to dump it into a heap of runes into more RP, whereas 2H focusing on getting runes up seems harder.
I don't know if it's just me, but it feels like out of the two specs, it's a lot easier to play as DW. (Slower play style too I think though, ie. more empty GCDs)
