[RP] Rune of Cleaving cooldown

[lyncher12]

With the mirroring of the armor debuff tactic for the aoe dot I believe that the cooldown for Rune of Cleaving should be reduced to 5 seconds like Demon Spittle is. It is a high risk, high reward tactic and competes with a lot of other really good tactics. If it disrupts it feels like a waste because you don't have a tactic for 10 seconds. You obviously aren't going to activate Rune of Breaking just to pop this dot if you are playing a heal RP and it doesn't make sense for a dps RP to even take this tactic.
