When can we see Arcanist / Summoner in action?

[Elexia]

I thought they had said arcanist WILL be in the release of ARR but the SMN will come with a later patch. Apparently they already had the arcanist in the gamedata since 1.0 beta but they never implemented it. Now they are just re-purposing it for the SMN.

Yep, same with Musketeer which had some basic data with it. SMN I doubt we'll ever see till beta time if at all especially since unless they're just being fancy with words, they're over complicating it simply because they don't want to see 'copies' of a summon so they're probably having issues with it functioning just like they had issues with Odin and Alexander functioning properly in XI.
