Perma question for every powerset

Its the exact same formula. You just need to look at it different. The Recharge Time in the Formula you want to be equal to duration. so, just plug in the numbers until it matches, that is the number you need.
RechargeTime = BaseRechargeTime / ( 100% + Buffs - Debuffs )
So, for Brute Dull pain the Recharge time is 360s. The duration is 120s. You want Recharge time to be 120s.
120 = 360 / ( 100% + X ), when x is 200 the denominator is 3, dividing 360/3 which gives you the 120s you are shooting for.
Another way of saying this is to make Duration = D, and Base Recharge = BR. In this case 120=D, and 360 = BR. The formula would be D = BR / (100% + X ). Rewritten this formula is ( BR / D ) = ( 100% + X ). That tells you that you need Base Recharge/Duration to equal ( 100% + X ). In this case 360/120 = 3. So ( 100% + X ) needs to be 300%, and X needs to be 200%
So, always divide your Base Recharge by the Duration. This gives you a number, in this case 3. The percentage needs to be that number, and you start with a 100% free.
Solve for:
Duration = Recharge Time + Activation
Duration = BaseRechargeTime / (100% + Buffs - Debuffs) + Activation
(100% + Buffs - Debuffs)(Duration - Activation) = BaseRechargeTime
(100% + Buffs - Debuffs) = BaseRechargeTime/(Duration - Activation)
Buffs = BaseRechargeTime/(Duration-Activation) + Debuffs - 100%
Buffs include recharge enhancements, recharge boosts from powers and temporary powers (on a perma basis - calculating with non-perma hasten gets a bit more complicated) and recharge boosts from invention bonuses.
Debuffs are recharge slows experienced. Essentially, more recharge than you need for perma counteracts perma debuffs on a 1-for-1 basis.

Huh.

Given:
1. RechargeTime = BaseRechargeTime / (100% + Buffs - Debuffs)
2. RechargeTime = PowerDuration
3. Debuffs = 0%
Prove that:
1. Buffs = (BaseRechargeTime / PowerDuration) - 100%
Proof:
1. Multiply both sides by (100% + Buffs - Debuffs)
RechargeTime * (100% + Buffs - Debuffs) = BaseRechargeTime
2. Divide Both Sides by RechargeTime
100% + Buffs - Debuffs = BaseRechargeTime / RechargeTime
3. Subtract 100% from both sides
Buffs - Debuffs = (BaseRechargeTime / RechargeTime) - 100%
4. Set RechargeTime = PowerDuration and Debuffs = 0%
Buffs = (BaseRechargeTime / PowerDuration) - 100%

One quick thing to check with, however - if you want to see if a power can be perma, divide it's recharge time by five. Recharge cap is +400%, so if you divide by five and it's still above the duration, it can't be perma.

Wow. If you look at a power and it requires more than 200% bonus above the 100% you are given, and you still think you can do it... Just wow. And gratz if you do.

Perma-Hasten requires +275% and plenty of people manage to perma that. In general you can probably hit close to +300% recharge without external buffs on most characters (95% in the power, 100% from IOs, 70% from Hasten, 32% from Spiritual Alpha). Hitting the recharge cap is at least theoretically possible on a Time character* although in practice it's probably not worth doing.|

No, that does not make auto-firing it a bad idea - in my opinion.
All of my toons with perma-hasten, or anywhere near perma, have it auto-fire.

Also worth mentioning: There are at least 2 powers that the recharge time and duration would seem to indicate that they can be made perma, but they are completely unaffected by recharge boosts of any kind, and thus cannot be.
They are Strength of Will and One with the Shield. You should be able to infer which powersets those powers are found in by their names.

I'd forgotten about the end crash. Frankly, I never notice it on my main, who keeps Hasten on auto-fire (only about 8 seconds down time between Hasten expiring, and re-firing). The end crash shouldn't be a factor in determining whether to auto fire or not. IMO.

Q. Just wondering Posi, where are the new dance emotes we were told would come with GR?

Well, there are a lot of powers that would be better perma, so I was wondering if there was anything on how to get there.
Wiki has the classics which instantly helped me
RechargeTime = BaseRechargeTime / ( 100% + Buffs - Debuffs )
where Buffs includes all bonuses mentioned above. A 100% enhancement thus cuts the recharge time in half. A 200% enhancement cuts it by two thirds. Since the enhancement is in the denominator, it is subject to diminishing returns the more you add, the less each new amount helps.
I mean for things such as Mind Link or Tar Patch, which can be found by playing about in Mids, but I was hoping for a less intensive non-Mids solution to knock around with.
Feel free to point me at the guide I missed that has lots of powers listed.
Some day I will work on a perma-dom and maybe finally enjoy the AT, but for now this would be enough.
