Accuracy and Purple set bonuses

I have returned from a long break and have little experience with the IO/Set Bonuses system that I believe were implemented in I9

Goal: To rely on only set bonus accuracy. Is this do-able or is this not realistic?
If no, disregard the below

Assume influence/infamy is a non-issue. I realize some sets/recipes are mega-expensive

Assume there is no Tactics or outside help to improve my ToHit

Assume there is no reduction to my foes defense/defense debuff

If I wanted to completely eliminate the need to slot specifically for accuracy in most/all powers (except of course when I want to get set bonuses and slotting some accuracy is unavoidable) what's the magic number of % of accuracy I would want to aim for via set bonuses to be at (or pretty much at) the "hit cap" when facing AV's that are level 53. Or level 54, atm I can't remember if there are 54 AV's.

Hope I explained that very clearly, and thanks for your help in advance!

Also don't forget that the unique IO from the Kismet defense set gives a global to hit buff as opposed to global accuracy. You'll want to slot that in a defense power.

By slotting your attack powers specifically for accuracy bonuses (purples, thunderstikes, crushing impacts, sirocco's, etc) you'll often need to slot IOs with accuracy in them. I usually end up with around 40% accuracy in my attacks just by slotting IO sets, whether I want the extra accuracy or not.

In particular, frankenslotting or semi-frankenslotting (going for the 3rd or 4th set bonus in a set and then frankenslotting in triples or quads to maximize enhancement) will likely result in some accuracy almost unavoidably.

One of my current projects slotted this way, winding up with 40-60 accuracy baseline in the various attacks....and 5 sets with the +9 global acc bonus (for +45)...and one Purple set (for +15 bonus). +60 global acc bonus is very nice when added to a moderate baseline acc enhancement.

As mentioned, it's almost impossible to get a high bonus in accuracy without slotting some accuracy in a bunch of powers.

I would like to also mention that I slot a lot less accuracy in general than most people. I'm happy with 50% -ish in most powers on most characters. There's a lot of powers that have built-in To Hit bonuses, there are a lot of teammate "accidental" To Hit bonuses and defense debuffs (got Fort? got AM? anyone hitting with AR/broadsword/katana? any rad powers? ) , and there's not really a lot out there that does much dodging. So my trays fill up with yellows and I convert them into other things.

Depending on the PP, they may also be running "10% hit points, 90% resist" at the same time, so when you DO hit you're doing single-digit amounts of damage. I recommend something like "stacked holds" or "Well-timed knockdown" combined with rapidly delivered, overwhelming damage. One nasty trick my SG's latest team has been using is "no endurance, no Moment of Glory".

( Read the text on small vs. medium vs. large yellows; you really CAN'T eat enough smalls to make a difference. )

Certain psi-based powers like Blind, Mesmerize, and Dominate are great on Paragon Protectors... they have no positional damage component and do psi damage so they cut right through the various Elude / MoG powers. If you don't have that sort of attack you can also (briefly) hit them with Aim. Since Accuracy only multiplies your base to-hit (which is very low against Elude without to-hit buffs) you'd need impossible amounts of accuracy with no to-hit buffs, but a lot of accuracy can significantly boost what to-hit buffs you do have. For instance, eating yellows with +100% accuracy from global bonuses and enhancements is twice as good as eating the same number of yellows with no accuracy slotted.

(If you want to see Paragon Protectors absolutely fall to pieces, send multiple Illusion / Rad or Mind / Rad Controllers after them. )
