You know that was done because it was a poor poor 2 hour! You can't give us procs for NMs and buffs tied to the wyvern being alive and then leave it on a twenty minute recast, even with the additions to help keep it alive (which I do love, lets not get me wrong) it just isnt enough to keep the wyvern around when it's needed. One AoE from most of the higher tier VWNMs does enough damage to kill the wyvern or leave you terror'd, para'd , amnesia'd to a state where you can't cure it. I'm fine with it dying, but then sitting there for 18 minutes saying you're sorry but no Breath procs is embarrassing.
