Fast Paced ARPG. NO?

Bosses just around the map off screen to off screen. Hordes of enemies swarming me. Dodging, rolling, tumbling, skipping, doo dah day?! BUT my skills require me to sit still for 2 to 3 seconds to even have a chance to cast? How can you make fights so fast acting where milli-second reactions are REQUIRED but the skills needed to survive fight and live pin you in place for 1.99 seconds to long to be able to live? GGG asks me to kill 30 things in 6 seconds but gives me tools to kill ZERO cause I'm stuck standing still being interrupted for 8 hours now...
Yes with RNG gods all roll perfect 7's across the board 308,921 times I win but otherwise I get a barbed wire wrapped bat right up the ole *$$. If that's fun defined society as whole is ready for post nuclear life..
