Okay, guys, so it's been a while since I posted a good thing on these forums. That being said, as you all know, the 2.4 patch notes make it so that using Rocket Boots Xtreme will drop a flag in PvP, preventing the popular Engineer "slowfall+boots" trick.
Well, it might seem like common sense to some, but they would dismiss the thought as being trivial. Despite that, I tested it anyway.
And I can say that, if you DROP the flag while carrying it, THEN use the Rocket Boots, and then PICK the flag back up before the buff runs out, you can still proceed to rocket with the flag. That being said, you will be unable to rocket jump when people are attacking you any more, but you can still do it when there isn't any "opposition".
So once again, if you drop the flag in WSG, and then use Rocket Boots Xtreme and pick the flag back up fast, it will not cause the flag to redrop. Only the original action of using the boots drops the flag.
Happy battlegrounds be upon you, fellows!
