That guy is 100% right.
Legends is flat out better than those fucking games and they should be fucking ashamed.
Why?
Because Legends is a free mode ofcourse. But it has solid mechanics that aren't just based around DPS. Ofcourse its better to be on level (which works with Gear score), but you do level up appropriately after beating all Bronze, and then all Silver. You're likely close to 80 and you can beat Gold if you're slightly underleveled. Because this game is also about skill. Playing smart by picking off the right enemies, having a good bow aim (or using hallucination on those pesky Oni), parrying and blocking helps you just as much as it did in the story mode. Having good levels and gear makes the margin of error bigger, and your damage higher which means you have a more efficient time. But its not impossible.
Also, the missions are legit good. Teamwork is required. There aren't many levels, 10 ish and 4 survival, but the modifiers keep them fresh. Sometimes you have the element modifier thrown in and you need appropriate colors to beat the enemies. This means your team mate needs to pick the other color and attack his own enemies. Most of the time it works, sometimes I'm thrown in with what seems to be an oblivious player but after some pinging he gets it. I beat this weeks Story Nightmare mode with a random who was on point with everything. Though I also failed a shit ton. But this is the hardest challenge in the mode, I was even surprised I could fully beat it with a random. And it was hard as balls, that fucking last enemy wave.
The classes are good. I'm rocking a hunter (which is likely the most broken class right now), I am consistently scoring highest kills in Gold survival. I don't have the Legendary Longbow yet (its my goal), but I have a build based on headshot damage, ranged damage, Fire DoT damage bonus and effect duration. In short, my fire is causing some serious shit. I just see the health bars depleting. I also rolled an epic sticky bomb with ignite, near max blast radius and damage bonus. I do have the legendary, but its not as good imho (despite the damage heals your team perk). I rather slot the Masamune with maxed Damage and Oni Damage bonus, it has 20% chance to deal double damage on top. But its just Wind stance. I'll bench it once I have the longbow, lol. 2 Legendaries is an option, but you lose the 50% body shot = headshot damage chance. I also have the Legendary Caltrops which I love, it causes Weaken, stunlock and I have the perk that increases the number of caltrops thrown.
