Only one i can really answer is 4. I use macros on my berserk, holmgang, and thrill of battle. Depending if you use macros for your basic actions or not, you can set a wait 20 on berserk macro as well to warn when you're about to get the pacification. thrill is good to let your healers know when they have the chance to pop a big stoneskin on you. and holmgang just lets people know 2 things, that the mob isn't moving for a short time, and that they can focus heals on other targets for 5 seconds before picking you back up quickly.
