Reducing the Dark Rune and Demonic Rune cooldowns during the level 60 phases?

[Talthos]

Rather, on retail, both Dark Runes and Demonic Runes had a 2 minute cooldown during both Vanilla and the entirety of TBC (even Patch 2.4.3).

Their cooldowns weren't nerfed to 15 minutes until the Wrath patches (3.0 patch numbers and onwards), long after they stopped being truly relevant in PvE.

But since we're going with 'progression' on this server, and considering how long it'll be before we can ever expect to see Northrend, why not let Dark Runes and Demonic Runes be relevant again, at least for the level 60 phases?
