Not sure why I'm replying to this but I feel compelled to state that when we first BLM burned Garuda we were not aiming to "use an exploit." Timing when not to attack and when to go full on zerg is a strategy that we used for ourselves in the past for a stronghold NM that spawns an army of adds at every 25% HP. We started this there in order to gain, save and have at the ready the kill power (TP, MP) to zerg it down before we were overwhelmed by 50 additional mobs. If we went too hard too soon we would sometimes run out of gas before it would die and be overwhelmed and killed while struggling to finish him at 5% health. That was the strategy that we used to kill Garuda before Aerial Blast. We were not plotting how to cheat the fight or take advantage of an oversight on the part of the developers. Our aim was to be innovative, not to exploit a flaw in the design.
Ironically enough, we have likely benefited from our 3:30 kill strategy less than 95% of the people who have seen and replicated it. I think we've done Garuda a grand total of six times since making the video public and feel no immediate rush to zerg all the weapons to completion since they're not that incredible and we're capable of beating it any number of ways with any number of classes.
Darklight bodies are more important to us than glowing wind staves.
I will say the fight (as intended) is the most fun of any content SE has given us to date. I admit and agree that it's unfortunate few people will need it or be interested by the time the AI is changed to trigger Aerial Blast at a set HP% regardless of time or damage.
I don't think the real issue is `class stacking` or dev oversights. The real issue is limited content which we assume 2.0 will remedy. If the game has plenty to do, with high end and extremely challenging endgame content for parties as well as alliances, I highly doubt people will be that worried about who is getting Garuda weapons in a BLM party.
