Seems you didn't get my point, you said "cause I know for a fact its hard to survive with it", that's why I said it's for noobs, if you can combo with 2 SD you don't need the whole set with this option, because you'll die faster if you do, for me it's better to use only 2 SD so you can have a lil more of defense with 3 DDR in your set. That's why I said "noob", I mean, if you can combo with 2 SD, why would you use full SD so your defense will suck? If you can't combo with 2 SD you're a noob, that's why I said "full SD is for noobs", because if you're using it it's cause you're not good enough with only 2 parts of SD, hope it's clear now.
By the way I don't think that if you can't combo with 2 SD you're a noob, it's just a say.
