Apparently the "Incoming!" shout was intended as spike counter tool.
Unfortunately 50% damage reduction with durations 1..7 sec became damage migitation tool instead of spike counter. So they nerfed it to 1..3 sec.
I think that it might be much more logical to rather change its functionality to get rid of the whole damage migitation aspect and go for pure spike counter:
"Incoming!" [e] Shout
10e 0 cast 13 recharge
For the next 1..5 sec all allies within earshot share all received damage with their closest ally within earshot(to prevent a solo charcter from sharing damage across whole map).
This would double the HP pool of player vs spikes, but wouldn't lessen damage taken as a party.
Do you think this could be a good solution?
