Will the new Squad Commander and Devotion to X titles be retroactive if we have the kill 1000 enemies achievements pre-4.0?
Edited to reflect both titles.
That is correct, there are no Influence Achievements planned to be live in Fallen Empire. However, we certainly could add them in the future (and have them be retroactive).
Does it mean there won't be any new Influence achievements either (i.e. "Reach Influence 10 with Lana")?
