O.o.... Man, you would have to give up something REALLY powerful for these to not be OP builds that you would end up required to use.
As a side note, though... Do you know that Shield Swipe used to not be based off of blocking? It used to be an on-GCD skill that cost 60 TP. No one used it because it was a horrible DPS loss. They changed it to be what it is to make it MORE useful, which it is and you should be using it when it procs.
First, the system wouldn't be able to be limited to just when you're with your static. Second, those can be steamrolled through because everyone coming in sees the jobs and knows what tools they can expect to see. Also, sorry to break this to you, but in an age of 'pull as soon as it loads', no one is going to wait for you to respec. People don't even wait for Protect anymore.
