SuperReflexes....To Hasten or Not To Hasten??

Claws/SR is probably the NUMBER ONE build in this game, that i would never even slightly consider picking up hasten on. Claws with any armor for one doens't need hasten. Likewise, that falls on a claws build more to the secondary, of which, nothing in SR needs hasten for. Only elude might be the only case, but when you can easily soft cap the build anyways, that goes out the window as well. Please do yourself a favor and relish in the glory of a claw/sr without hasten, you'll be much happier.

As to quickness, it should be around 30-33% recharge bonus, but I don't think that the devs would even consider doing that at this point. They don't even let you have combat jumping on at the same time as ninja run right now, if they're being that dumbfoundedly stubborn about something like that I can't imagine they'd look twice at something like boosting quickness. The SR set in itself could still use some tweaks though, but again the devs don't seem to care about things that can be boosted with IOs even if they are somewhat sub-par before them, which wasn't supposed to be the case to begin with either :/, oh well we can fight about that all we want but the Devs probably woudln't budge one bit about something like that at this stage in the game.

Obviously my opinion isn't as prized as that of those who have a higher post count or who have an earlier join date than mine....I will put my 2 cents in anyway.

I take Hasten on pretty much all my alts, regardless of AT & power set combos.
I consider more recharge a good thing in all circumstances.

Even a lowly FF/AR defender will benefit from Hasten greater than he would from Hover for the simple fact that greater recharge means your heavier hitting powers will come up more quicker.

I also take Super Speed on all my alts regardless of concept.
It's easy for me since all of my alts are of a supernatural origin of some kind or another.

I now return you to the opinions of CoH/V vets.

FF/AR actually gets very good use out of hasten. FF doesn't need a lick of it except for perhaps repulsion bomb, but with the aoe nature of AR, and the weaker damage version defenders have to deal with its a very good power for a FF/AR. With SR though, you don't need it for SR at all, so you are looking completely to the primary to see if you need it. Claws certainly doesn't, katana doesn't either. Optimizing BS builds might consider it, but i certainly wouldn't. The only SR biuld I could see taking it on is either elec/sr or spine/sr if you want to consider to some-what farm with them, or possibly fire/sr for the same reason/ AV soloing. DB doesn't need it, MA doensn't need it, for the most part DM doesn't either, except again unless trying to solo an AV and you're maximizing it for that.

Force Feedback doesn't have a 100% chance to proc, much less a 100% uptime ratio. Turn it off and you'll realize that you only have 76.3% global +rech.

I don't have a Forcefeedback IO set on my build and I get 176.3% haste without hasten. Now this is Mids numbers, I'm not in game atm to see my actual numbers from my Combat Attributes, but I have no down time on Practice Brawler.

There's explicitly no way to turn on two powers with one keystroke.

However, you can try to bind one power execution with pressing a key and another with releasing it. I don't find it works that reliably, because I click the key too fast and the server ends up only doing one of the things I wanted. Occasionally lag is also an issue. I swear that keystrokes get delivered out of order when you're suffering bad latency spikes.

I went with the easy solution.

g for sprint
b for ninja run
h for combat jumping or hover
v for self heals if one exists
j for super jump or fly or superspeed

Since it's the same on every character I have, it's become second nature.
