Guild Wars 2

I was fiddling arround some builds of mine and notice that several runes have HUGE icd without any reasoning.
Especcially rata sum and grove runes.

Grove runes have a wopping 90s cd on one root. -> ancient seeds from druid has 10s . It would be nice to give this rune a cd reduction it would be in good use for condi druids.

Rata Sum runes also have this huge 90s cd for a 15s radiation field. Even the normal skill itself has a smaller cd of 60s which is still to high. Something about 30s would be nice and could give some new opportunities for poison builds.

If someone has some other runes as subject to change please join.
I would also apprecciate some other viewpoints and opinions.

The ICD of Ancient Seeds is what’s wrong, not the other way around.
