So, during those "Invasion" events every three hours, I noticed that the boss drops changed. Before, they'd drop both Legendary and Epic equipment, but now they only give one Epic piece of equipment. When did this change? It was one of the more reliable ways to get Legendary equipment, at least for me :/

I think Equipment drops got changed when we implemented the big list of changes a month or two ago.

Legendary Equipment now can come from Dungeon Bosses and from Mission Satchels.

I don't think it's a good change. As it was mentioned, invasions were a good source of legendary equip that is not tied to a 24 hour cooldown.

It wasn't intentional IIRC. I think there was a bug and the only way I could fix it was copy/pasting code from Region 3.

Ahhh alright! Dang, that sucks. Is there no way to set legendaries to drop from invasion bosses anymore then?
Also, I don't know if I'm imagining it, but when I had just started, I think invasions had three waves before a boss spawned. First, second, then final wave, then boss. Am I just imagining, am I overlooking something or was this changed?

If something with that changed, it wasn't intentional. Haha.

It was a pain to 'retrofit' regions 1 and 2 for all of the changes that were made a bit ago and it's very possible some things got tweaked unintentionally.

As for adding the equipment back, yea, it'd be possible. I'd just have to try and scour through everything to make sure there wouldn't be any further unintended consequences.

Code sure is an adventure, huh? xD
No harm done. It would be amazing if you could look into it, though.
Invasions are amazing leveling helpers, and more waves means more experience for the pets to be leveled. And the legendary drops really help gearing up for grinding out dungeon runs for mythics!
If it would be no hassle to you, I'd love a notification on whether tweaking things back to what they were like before ends up being possible or not :3 Don't know if it's a big enough thing to make a full announcement.

I'll try.

Often the issue is I have literally dozens of these 'little' things to do and I could spend solid weeks working on them all. But like, atm, I'm focused on trying to progress the MegaZone so I don't want to get distracted with all of these side chores.

So they kinda just stay off to the side until I find a day or two to go through as many as I can.

The issue with this specific tweak is the original zone code is really old and really poorly structured. It's very easy to change the most minor thing and have the craziest results - both because it's poorly coded and because it's been so long I don't 100% remember how it's set up.

But I'll try to keep it in mind for whenever I get a chance to take a look into it.

Of course, focus on the important things! I wouldn't ask for things to be done immediately, I don't care how long it takes, I'm just glad it's going to be looked into if you can manage to.
So IF you get around to it, whenever that may be, I'd love to get to know.
Super super looking forward to the MegaZone, btw! :D I hope I'll be prepared when it arrives!

I understand that it's not an easy fix, and appreciate that you explain why it's such an issue to work on it.
Thank you Krin!

It's super appreciated for sure! Again, thank you so much! ^-^

Regarding waves, only the town and sanctuary raids had 3 waves, while the other zones' raids had 2 waves. So since the festival is ongoing, and no raids happen in the town/sanctuary during festivals, the current raids only have 2 waves.
