I've already made a thread about this, and received a response;

I even originally called it "Yoshi-P, give me the D", till they renamed it.

Currently only 3 markers are available for use, whilst they're a completely invaluable boost to most co-coordinating your party through content. Seeing as most arenas have;

Four corners,
Four places to run,
Four things to run TO,
Four things to run FROM.


Anyone else feel it would be a nice addition in the future? (Only for ONE more marker, not several).




THIS IS A REQUEST, not a demand.

I can understand as with every request it's importance isn't a high one, however this would be a nice addition to raiding content as opposed to calling 'D' the "Opposite" side.
