With the addition of the Class-based Global Buffs, they appear in FRONT of the usual Incoming Buffs. It would be much better when checking out still-linked nodes if those Global buffs would appear AFTER the Linked Incoming ones. The Linked buffs are the ones your are interested in.
And besides that, these new Global buffs don't even appear similar to the already existing global Attack/Health buff that comes out to everyone from the boss (or node before boss). Thus even more inconsistency when these new class-based ones are displayed in Purple, making it appear that a teammate has to unlink your path first. See pic from a lower group, but is especially a problem in Map-7 with so many of both Self Buffs and Linked Buffs.
And a side note about Map-7, why did killing miniboss Omega Red fail to generate an auto-message saying so in BG chat pane ? I thought miniboss kills always generated “kill” messages in the chat.
