Quick question about martial arts/super reflexes
You can get away with taking all but elude from super reflexes. With IO slotting you can get to the def cap rending elude kinda useless.
Quickness is a nice power, i would not recommend skipping it. You don't really need quickness.
Stamina is never required, but it'll make your life easier, much easier 
. And it's the other way around really. The toggles aren't that costly, it's the attacks that'll drain you. They're quick and rather heavy on end.
There's a few MA/SR build in this thread might give you some ideas for which powers to take and how to slot em.
Yeah what Neko said. I find SR more easy to handle than WP before QR or Invulnerability endurance cost wise.
Also keep in mind not all MA powers are good. It is personal choice but i see more skipable powers in MA than SR.
Quickness is awesome when leveling. It allows you to do heavier end redux slotting in attacks, something ma needs.
I started building this character out of curiosity and to my surprise it quickly became one of my favorites. I have a pair of questions that bug me,though.....
) The attacks consume little endurance,but the toggles seem to burn lots:should i take it?
first of all,to a new player like me,it sounds like if you want to have a good defense,you have to take ALL the powers from super reflexes; wich doesn't sound like a very feasible thing,considering how many good attacks you can chose,travel powers,power pools etc.
So i am seeking some kind of advice for this matter:wich powers are a must,wich are not,and how to slot them effectively.
Also,how good is quickness? Usually i take hasten for my characters,but in this case i was wondering if i can skip that and use quickness instead,seeing as how martial arts gets low recharge times anyway and has a good number of attacks
Last,is it stamina required? (i imagine the answer is yes
Any tips would be appreciated
