Did you know that with the new talent Empyreal Ward announced for paladins in 11.0.5, Lay on Hands becomes a 30 second damage amp for warriors?
Warriors have a strong throughput talent right now that converts armor to strength, I saw a video where Critcake estimated the ST value of each point they put in that talent at around 4% of fury’s total damage, for about 8% total contribution with 2 points invested.
Double your warrior’s armor, double the benefit from that talent, for 30s!
Lay on Hands may be useful for saving lives, but your warrior will surely appreciate having it used on them on the pull for their burst window instead.
