[Solo Gauntlet in Festival of the Four Winds]

Can anyone recommend a build and strategy for Blobs/Schmobs on a Guardian? I've got a FB build, but I can't do it without killing some of the other oozes. This is driving me crazy!

[Help needed: Blobs, Schmobs for Guardian]

Can anyone recommend a nice, easy build for Guardian that isn't fiddly to operate? I'm trying to get this achievement, but the dragonhunter pulling approach doesn't seem to be working for me, and the only Youtube videos I found for guardian are hopelessly out of date. Any tips would be much appreciated!
