Key phrasing in that is:
Quote:up to three hours per potion. NOTE: You need to have unlocked the appropriate Epic Destiny before you can gain experience in it.
Will be interesting to see what the point cost is on those. Might be useful for alts and whatnot, but depends entirely on how much SSG decides to gouge the whales for the privilege of being lazy.
It will be very easy for SSG to price these too high to be worthwhile. These days it's not hard to roll a variety of TR zerging builds that work well with the various destinies.
Swash barbarian, tempest ranger , wraps monk, etc. work for melee destinies. Shuricannon, rogue mech gxbow or inquisitor dual xbow for ranged destinies. Full evo fire sorc for the caster destinies.
Full evo+spellpower sorcs are so roflstomp OP'd in elite/low reaper content right now that they're probably the fastest option for leveling any of the destinies. Meta'd SLA fireball with fire savant capstone to remove fire immunity --> meta'd DBF --> meta'd Meteor Swarm = everything short of rednamed is already dead.
Or there's always the good ol' nerflocks for the people stuck in 2017's meta. Not what they used to be and definitely lacking compared to sorcerors, but they'll still get the job done well enough.
