Are people actually weapon juggling or is at online theorycrafting?
For perhaps the first time ever, I am actually with you on this one. I've played in three campaigns since 5.5e launched (well, one was just before the official launch) and I've seen exactly none of the "juggling" folks talk about here. Instead, I've seen quite a bit more dual-wielding than I had previously. The only thing even remotely approximating "weapon juggling" is that the warlock in my current game will occasionally call in different weapons with his Pact Weapon feature, and he
tries to call in ones that would be useful in conjunction with his Fighter levels. As it stands though, it's nothing like the nightmare scenario described upthread where you have a single PC juggling 3+ weapons nearly every round of combat in the slowest and most laborious way.
Which is honestly really frustrating because that presents this idea that it's somehow
specially bad that a Fighter or Paladin (or whatever) might do this....when this sort of hemming-and-hawing, "juggling" options, etc. has been a perennial problem of (neo-)Vancian spellcasters for literally half a century at this point. Fighters having the teeniest, tiniest, most vaguely pseudo-similar situation is a HUGE PROBLEM, but full casters having a much more thoroughgoing version of this problem is totally okay? Yeah, sure, pull the other one.
