Correct me if I'm wrong but both IPad1 and iOS5 are pretty old at this point right? Might this be the machine? Game is perfforming OK for me right now (not great but not as bad as it has been before). Anyone have better input?
To my knowledge the double/triple strike just multiplies the points/loot you get (wd, bp, cash, xp, valor etc) by x2 or x3. Its actually one attack so I'm not sure what you mean by the equipment stats go down for subsequent attacks.
