Tohit and Defense
Short answer: yes.
Long answer: yes, but with some complications. Basically, against even-level enemies with normal ToHit chances, a -ToHit debuff of 15% is exactly equivalent to a 15% Def buff on your pets.
However, that defense buff will always be 15%, but against higher level enemies, the -15% ToHit debuff will get weakened, meaning that it's not quite as effective as the Defense buff.

I'm sure you'll get a number of responses, but I think you'd be well served to read the
following 2 articles on the wiki site:
http://wiki.cohtitan.com/wiki/Attack_Mechanics
http://wiki.cohtitan.com/wiki/Purple_Patch
The Cliff Notes answers is yes, but... (purple patch will explain the "but")
Global = Hedgefund (or some derivation thereof)
They're... roughly equivalent. Basically, Defense is subtracted from To-Hit to get the actual chance an attack will connect. So an enemy with a 75% to-hit chance attacking a character with a 30% defense has a 45% chance for the attack to actually hit.
There are times buffing one is better than debuffing the other or vice versa, though. The wiki explains it better than I would.
FUN FACT: That burst of light when you level up is actually the effectiveness escaping from your enhancements all at once.
Defense will protect you and your affected allies from enemies.
-ToHit will protect you and your allies from affected enemies.
Aside from the purple patch, AVs also heavily resist -tohit. So -tohit becomes less and less valuable compared to +defense when you face higher level foes and/or AVs. AVs will pretty much just laugh at your tohit debuffs.
Good to know, thanks everyone. I learned Jounin has its own buffs, sometimes for 50% def, so I'm not too worried.
Even running on highest difficulty, while it may be less effective than a def buff, it's still pretty effective.
I'll just through this out there, Ideally you want both, -to hit and defense work great with each other, there is a very good reason why Scorpian Shield is the best epic/Patron toggle for Rads, Darks, and other -to-hit debuffers
Is a power which debuffs tohit, the equivalent to a power that buffs defense?
I am looking at /Time Manipulation for a Ninjas MM.
Ninjas already have great defense, and the +15% def from foresight puts the Jonin at about 30% Def(All). However Time's Juncture can give -15% Tohit. If this was equivalent to +Def, it would give Jonin the equiv of 45% Def(All).
Does anyone know the relationship between the two?
