I won't attack y'all with a wall of the text, but long story short is I believe the class balanced patch further isolate the bossing parties to all ranged classes as the most efficient party instead of a healthy mixed with melee and ranged. Please keep the thread, language, and attitude positive even though this topic is somewhat negative.
It's just easier to have a faster run with just ranged classes. Paladin's new cancel buff is a very good one, but the buff itself doesn't really need the presence of a person playing it in a party. Most people trying to fight end game bosses with ranged classes will be washed enough to not rely on HB so one of the ways that both melee and ranged can have a balance in a boss fight is 1. boss summons a ridiculous amount repeatedly which leaves ranged classes with no room for attack a good amount of a run. 2.boss spams weapon cancel so frequently to the point it becomes a Paladin/mage exclusive boss. 3.boss has a large body, a high knock back rate and walks super fast making it difficult for ranged to keep distance and need warriors for the knock back and rush. Those are one of the few ways I feel would make a better balance of ranged and warriors in a fight. Even the Toad boss which seems to be made for tanky classes can be played with ranged that hp washed.
