While i do not time my runs i went ahead and timed Strat Live side with my team.

Running Deep Prot War (35/11/5) / Holy Disc Priest ( 30/21) / Deep Fire Arcane Mage x2 ( 34/14/3) / Elemental Resto Shaman ( 31/20) , took me 34 min to clear the entire live side (including Timmy and the useless paladin Malor) with shaman dead at Balnazzar (he got 1shoted right before the metamorphose all team got stunned i lost thread) .

Even if watching multiple ppl running 4M1P / 4L1P i dont see the point in running without a tank , yes you gain 3-5min per dungeon but you cannot do certain bosses (id like to see Baron killed with 4M1P , or even Lord Alexei ....) and even high chance of wipeing ....

Just my 2c ...
