Urgoz Warren mission(Cryway)?options

i have recently been doing urgoz with my guild. normally i play as ranger/rit, there is a hight demand for cryers in the team, they try to get at least 4 cryers in the teaam with cry of pain, but there require at least a sunspear rank of 9 or better, well on my ranger i have a tottal of 26 maxed titles, including max sunspear(10), can a ranger reroll as a ranger/ mesmer, with the required skills(cry of Pain, echo, arcane echo, either nigtmare or mind wrack), and still be effective, caause ther trying to do a cry spike, and with rank 10 sunspear i dont see any difference why a ranger could not fufill that roll????? You can, it can be done in VS farm runs. Also, drop Ether Nightmare. AS LONG as someone in the party is calling the appropriate target, there wont be an issue.

Ether Nightmare is rubbish, dont use it, not worth the 10 energy and 10 second duration.

Otherwise yeah it can be done. Good luck
