Slotting Damage Auras

They have a base accuracy of only 75%, so unless you are only fighting even con or lower things, 2 accuracies are needed, otherwise the aura will be missing a lot and just wasting your endurance, and your aura would be ineffective on those inane teams where they insist on fighting +4s and +5s since it would rarely ever hit.

Therefore, with just generics, 2 accuracies, 1 endurance reduction, and 3 damages would be ideal.

I'm not sure what gave you this impression but it's completely wrong. All damage auras have 1 base accuracy. Cloak of fear has reduced base accuracy but it isn't a damage aura sooooo...

It's also worth mentioning that damage auras get the full effect of any global accuracy bonuses you have. My KM/FA scrapper, for example, has the full five 9% bonuses just from slotting for other desirable bonuses. I would feel little guilt about completely forgoing accuracy slotting in his blazing aura as between the kismet, power siphon, and tactics/targeting drone as needed, +4s will get the same 5% chance to dodge that everything else has.

1 Base accuracy is 75% base accuracy.

CoF has 0.67 base accuracy, or 50.25% base accuracy.

Which reminds me, I noticed the Arma proc in my brute's blazing aura stopped triggering at some point, have tested it for several hours of gameplay now and its just no longer occurring. It worked when first slotted oh-so long ago, not sure what changed. Is there a Known Issue with the Armageddon proc and Blazing Aura power not working together?

Gotta do a respec in the near future, might pull the proc out and then slot it after giving it some time to "set".

Depends on your recharge. If you use Burn more often than once every 10 seconds then unique procs are better in Burn, if you use it less often then they may be better in the aura. However, you still have to consider that:

- Burn needs more slotting than an aura since it needs recharge rather than just accuracy, damage and endurance. That leaves less slots available for procs and due to the lower endurance cost Burn is actually viable for 6-slotting with Eradication or Obliteration for the set bonuses while auras aren't.

- Procs in auras check once every 10 seconds, regardless of what's around you. If you use Burn as part of your opening attack you'll have the most chances to proc, whereas in an aura it might fire early on when there are lots of targets or it might go off later when the minions have already dropped. (Only applies to characters with high AoE burst damage.)

- Some damage auras have a significantly larger radius than Burn and can hit more targets. Other don't, so that can affect your decision.

If you fight +2s or higher (common on teams) and don't have global accuracy bonuses or to-hit boosts you do indeed need two accuracy SOs per attack (possibly three in attacks with lower base accuracy). Even against +1s you'll only be at 85% to hit with one accuracy SO if you have no global accuracy or to-hit at all. If you are using SOs then presumably you don't have accuracy bonuses, so unless you have Tactics, Rage, or something similar (or you always team with people who give you to-hit bonuses) a second Accuracy SO is a good idea in most attacks.

Of course it's easy to just frankenslot most attacks to get 60% or so accuracy, endurance, and recharge plus ED capped damage and you can do so dirt cheap, so it's only pure SO builds that really need to worry much about it.
