Hello,

Can some advanced warden help me in choosing which ruby should i take, on which i will benefit more?
I'm warden in aspect of assault (dps)
I was thinking about 3 rubies : the one that makes higher crit chance of tornado from 50% to 75%
the one that makes tornado aoe and extend the bees by 0.3 (i'm not sure)
or the one in tornado greed that extends the buff which gives 12% more dmg for 15sec to 25sec.
Which should I take , or maybe none of those.
Waiting for an answear. Thanks in advance .
