Guild Wars 2

i got same weird salvage few days ago too – an item instead of giving me usual wood logs gave me 2 PLANKs – 1st time like that and i’m just wondering if this is something new in salvage loot table or just a bug? because it happened after last maintenance i think…

There should be another upgrade for the yak itself like that buff supervisor gets – if yak got hit by a player > buff kicks in for lets say 10-60 seconds depending on % of route it has to complete (closer the target – shorter buff duration).
That said it is still possible to kill/disable yak when buffed but alot harder to kill it by 1 player.
