I have completed all class Heirloom sets. Yes i want those uncompleted event drops.what are you asking about?
The water gun event drop? the dark lord sword event drop? Invader set drop? (not sure will comeback soon or not, because all 3 mention has appeared once for now, big chance will return, just don't know when.)
or you meant Heirloom set ticket? - this will surely be back in every event (unless new thing introduced)
Well, i going to give u a wet blanket.. Hehee..
Even if they return, we might not get them still. RNG still might screw us up.
