Meta gem for 20 PvE Guardian Druid

[Vichrae88]

I am building a 20 Guardian Druid for PvE, and am wondering what's the best meta gem. I have the Wastewalker set and was considering Brutal Earthstorm Diamond, @Chey's feral thread, the + damage has no effect. Is the Relentless Earthsiege Diamond a good alternative or is there another that would help improve my damage output?

If I had to use a meta, I’d probably do the tense unstable diamond, from the apexis event in blades edge.

guardian doesn’t hit very high numbers so 3% effect is kinda Garbo imo.

You also don’t have to use a meta gem either if you don’t like the options, instead use a 3 slot helm

Waste walker set is not that great, but procs are fun! So with that in mind I would use https://www.wowhead.com/wotlk/spell=55395/thundering-skyflare-diamond as your best option.
