Because Crucible was designed for those buffs. Crucible buffs have been adjusted many times to provide optimal crucible balance. They are a part of it. When you just say “Crucible performance” most of the time you mean 3b/VB (3 blessings without Ulzuin’s and Vanguard Banner). When naked performance is meant, most people add this modifier “naked.” 3b/vb is the norm. Naked is an extra.
Now, why is that? Because in SR you can (usually) pace yourself and take on mobs and bosses one at a time. In crucible you get swarmed from 4 sides. This makes debuffs stack 4 times faster and to levels unseen in main game (unless you leroy jenkins high SR boss rooms but that’s usually suicide). Those buffs provide a counter balance to that. Builds that can do naked 170 comfortably (over 50% consistency with average piloting) are very few.
Now, I don’t mind using pharma in builds. But if you write a guide this should be laid out for the reader, like: listen up, build is fine for 75 but you need to pop that Aetherward when you see Anasteria/Alex because there was no way around that aether res overcap. Or: health is lowly, build performs best with Ugden pharma. Or even put a little “pharma’ed” in the title.
This is important not only for the players but also for the devs who lurk these forums and don’t have all day to read every word. And then they nerf shit undeservedly (like Pyran, imo).
