I use it on my smaller account with Indom 2 only if it will give me the speed advantage and I am reasonably sure I will be able to take out my opponents dino. So if they have something with a speed that 10% to my speed will not beat, then I will not use it.
I never use it with Indo 2, its too easy to just cautious, cautious, definite, cautious, cautious, definite, cautious, cautious, definite, and win. At the very least, Indo g2 takes out 2 of their team every time using only cautious and definite. It really is ridiculous how OP Indo 2 is.
