Guild Wars 2

I used Fresh Air, D/F, GoEP, signet of water, and basically just tried to keep the dog permanently crippled and chilled. Works reasonably well, but you need to be lucky enough that the meat lands actually not right on top of the dog.

I also used the same tactic as Zantetsuken, but with 30 in arcane instead of water

I basically stayed where i was, at about max range, just weaving around left and right a bit and dodging in water for extra heal (sideways, to not get too close to subject 7). I think if you run in a circle, the slimes move too much, if you stay more or less put, they stay stacked together. They do a lot of damage though, so gratuitously use Swirling Winds and Obsidian Flesh to reduce damage taken, and take Signet of Restoration to passively heal while spamming all kinds of non-aoe things (thankfully S/F has few AoE skills).

The only potentially problematic skill is Phoenix, you need to be careful not to hit any slimes in its flight path (use it when you are to the right or left of the slimes when strafing around), everything else just spam on Subject 7 while switching to air in between every other attunement for the instant burst.

Different Question:
Did anyone successfully do the Chomper achievement on ele ? I am having a hard enough time to even beat him, let alone keep him from his meat.

Please make the note response faster when pressing a button with the horn, as well as make it possible to repeat the same note with less than a second or so in between. A lot of iconic brass/fanfare melodies require staccato on the same note. As it is, a lot of potential applications of the horn are impossible or have to be played very very slowly, even if one works around the major scale limitation.

Alternatively, at least change the behaviour when releasing and pressing the same note again to restart the note after the current default note length (thereby enabling at least moderately fast repeating of a note), instead of continuing the note if the time between release and re-press was not long enough.

tl;dr:
Make the horn more responsive, so we can actually play awesome stuff on it.

PS: Because people will surely argue that that would make the horn even more annoying, i would say the potential for trolling is big enough as it is with held notes, it can only get better
