A lot of people have been saying that this talent is not working but I’m here to tell you it is. I’ve tested this a bunch of times today and can confirm that the talent is working. I used a turret and watched the dmg numbers go up as it was hitting an NPC. I can not confirm heals as this was difficult to gauge without actual heal numbers in front of me (Ubi, maybe we could work this in later? Heal #s like there is dmg #s?). What I did learn was that the icon was not the icon for Rooted but an Offensive (crosshair) symbol and that the cooldown was not 25s but actually 60s/1min. So obviously some fixes need to be made to this talent but I can confirm that the talent itself is working...just not it’s icon or cooldown.
I'd say submit a ticket @ support.ubi.com, cuz who knows if the devs will ever read this post.
