Depending on peoples interest in completing Tequatl daily, I think this boss is perfectly fine. Today on SoR’s overflow we killed him with 5:58 left on the timer. Rumor has it that is the fastest LEGITIMATE kill in all of Guild Wars 2.
At this rate, the boss may need a future revamp. People are starting to learn the fight.
For those that think this fight is too difficult, try to look at other servers for guesting and just overall overflows. This boss fight is fine the way it is. The reason I say it may need a future revamp is because, like the previous launch of these world bosses, people found ways to make challenging bosses easy.
