As someone who has done a ton of WP SRs (15 mins and less, average right now is hovering around 14mins) there is just one thing I would like to say :

For the love of all that is holy wait for me to cast Stoneskin before you run off. I cannot count the amount of times a tank has been so impatient that they ran ahead because they couldn't wait the 2 seconds it takes to cast Stoneskin.

Seriously.

WAIT
FOR
STONESKIN

Thank you. ._.b
