Engineer WvW - Chill Stacking (New Build)

I made this build a little while ago and promised that I'd make a video about it. I completely forgot, but Mike W reminded me -thanks :)
All the footage is from the last day so nothing amazing - There were a few decent fights where I could demonstrate how strong the build can be though.
It's very difficult to kill as I can kite around dropping medpacks with reduced CD on block, as well as my heal and stealth coming off CD at 25% hp.
The chills are:
Swap to medkit - 6 sec long, 10 second CD
25% chance being hit - 6 sec long, 30 sec CD
30% chance on hit - 4 sec long, 10 sec CD (If using Ice sigil too)

Music:

Wild Culture - This Moment

[@alariczelen7099]

Anyone know what the stack max is for chill?

[@ProzapGW]

As far as I know, chill doesn't have a max number of applications (unlike immobilise, which is 3 stacks max). Every application of chill simply increases the duration by the amount denoted in the skill description, once the condi duration calculations have been run.

Btw why not sigil of hydromancy? And grenades kit?

[@ProzapGW]

Can take sigil of hydromancy instead, I just like the range on ice. In honesty I tend to use generosity and battle most of the time. As for grenades, I'm not really a fan - against anyone with half a brain they are not that useful. You would also lose a hell of a lot of survivability by losing toolkit.

[@ProzapGW]

Prozap GW Also, with hydromancy you would lose the ability to chill from stealth without breaking it.

[@d1namis]

Prozap GW interesting point (: chill from stealth, that realy interesting. I just like automated response more than elixirs. Thank for defining new usable rune. :D

[@ProzapGW]

Лев Зайцев No worries mate, always looking for new viable builds :)

[@d1namis]

[@ProzapGW]
