Its necessary to clear the 1st flashpoint (joint venture) to make others appear?

[BARBOSA (Aries)]

I just played the possible 15 of the 18 flashpoints on my "new game +" run. Now i´m reloading an older save to avoid the painful grind would be recovering rep from loathed, as i want to play the last 3 house exclusive FPs.

I wouldn´t mind that much, but do i have to play this FP again so soon, or i can just wait and the house FP will appear?

You don't have to play any Flashpoints. They will pop up and disappear 180 days later. No more than 5 or 6 will ever be active at once and it's a random draw for which ones show up so you can increase the chances of the Alliance Flashpoints showing up by completing the ones that do show up, but from a purely random position, the appropriate Alliance FPs should pop up eventually.
