Best Nuker for SF, FOW farming

So right now I have a ele/mo, and was wondering if I should change my secondary class to mesmer and get arcane echo to farm those areas. Is echo really that big of a deal after the patch?? Also if I do change 2ndary to mesmer can I change back and wil the skills still be there?

Echo'd Burst AoE not Sustained AoE works really well, Phoenix and Phoenix, or some of the Water spells.

thanks i'll keep that in mind

Also Spiteful Spirit is really nasty, Mark of Pain makes the creature it is cast on runs but you can body block that easily enough if using a MM

actually, if you have good teamwork, aoe overtime spells are better then ever, take advantage of the fact that monsters will run back and forth like retarded monkeys

I have used Double Energy Surge with some success but it's definitely a spike, not damage over time. Onfurtonately, it is a gold (and not so deservedly IMHO, I don't see it in the class of a many other elites), and your elite slot is much better served with something else. Although try this for fun, do the last missions (Abadon's Mouth or Hell's Precipice, I don't remember precisely which one but both will prolly work if they have bosses of your primary and secondary profession) with 2 sigcaps as E/Me, bring 1 elite as well, obviously, and arcane echo. I cried at the conclusion of the mission when it occured to me that I'll can never get used to having 4 elite skills in my skillbar again.

arcane echo shatter hex +energy surge does massive damage. At 15 domin, it does 120+120+80= 320 Aoe instant direct damage which ignore armor. Most importantly it doesn't cost exhaustion and mesmer can gain energy back while removing hex and interrupting(inspired hex and power drain).
