Wash # = hp for pb?

Youre making it sound way too easy. If it was as easy as you're making it out to be then people wouldn't be washing in the first place.

Also there's a difference between knowing something is coming and avoiding it all together.

Problem is, not many people know about the pattern or how to dodge the beams. Most people just assume that there's no way to avoid certain attacks in PB and put way too much emphasis on hp washing, which isn't even really that helpful unless you can get like 18k or 23k+ after hyperbody, which just isn't very realistic. Yes, it's possible to get hit with 10k damage while crossing (PB's magic/attack up buff strangely started working a couple patches ago), but that only unavoidably happens when crossing left anyways, so you can just wheel across.
