1) I've seen that to compensate the 46 BS you got Mastery of Focus, is that necessary? I used to think that the bonus from RR would be enough. So is it useful to go past 50?
My main focus is actually to reduce mezz resistance (The highest spell is only level 42). For non 50-song builds, you also increase both dd's as they are 43 and 44)
2) 37 in MA is compensated by +11 from gear and +RR, is it usefull any point above 50?
I would not argue that any + damage is not useful, but there is a low ROI when going high in the current state of Phoenix. I really wish there were some true options in terms of weapon-lines AND feather items Let's see what the survey results tell us
3) Damage wise, i see you prefer to have a huge AoG more than Aus. Str. or MoPain. Based on your experience is better to have a big dmg every 10 mins. than a sustained passive boost?
My playstyle is mainly solo. I often go long time without any viable encounters. Also i depend on several other actives so the timers tend to not be fully in sync. This means Ill usually have some tools up and sometimes have them all.
4) Magical damage wise, you got no boost at all, do you think DDs are not so important for skald?
DD damage is not very important, but the interrupt from DD's is absolute key. Additionally keep in mind that you are not always better off casting both DD's at the same time, but cast one and wait one second before casting the second could give a longer interrupt window.
5) Defence wise, you got no Avoidance of magic while a big boost in Parry with Mastery of Parrying, so skald is more vulnerable to phisical dmg than magical one?
I generally have little challenges related to dmg output vs casters and have downplayed this defence. Also note that as a Hammer user, parry = Stuns. And Stuns win fights
