Forum:Why won't my unit use their bursts in arena?

For some unknown reason my units won't use their burst abilities under any circumstances in the arena yet as soon as the opponents bursts are ready they use them every single time. It's cost me countless wins because either this game is broken or my units are stupid as fuck. I'm to the point where I have to search for people doing so much worse than me and I still can't always win just because my units refuse to use their bursts. If we could actually control our units in an arena like it should be then I'm sure everyone would be much more satisfied instead of getting stuck with stupid units.
