So the question of whether map 3 gives both or a choice is valid.
I see what you're saying after re-reading. If what you elude
to is correct, then it means after nerf'n events to the point
where the norm is to be 1 prize short ( artifact/set piece )
per event, yet the FA doesn't offer them, its a defacto paywall
even more than before.
So, since there was 3 events before the FA instead of 2, if
1 of each of the 3 isn't a prize, then effectively the paywall
has been put up. There are 3 maps, its simple to put 1 item
from each event as a main map prize, and it "appears" that
is Not what Inno has done.
Whats incidious about this is :
By not knowing Inno was going to do this, many players
chose not to "pay" , thinking a FA would get them the last
piece/artifact, that now seems impossible if Map 3 doesn't
offer both a Tinlug and Nexxus artifact.
