?? Why is that so hard? You just need to know how the game works.
All you need is a brief description of what the new content is going to be, and if you already know the timings of every other unit, weaknesses and strengths, you can figure out exactly how these commanders can be used to its fullest potential.
Anytime Relic released any information about a future patch or content release, tons of players including I have already devised exact strategies & build orders prior to release date. For example HelpingHans in his stream?
If you don't see the above analysis implemented on 25th onwards, call me a fool in this thread. If you're going to wait until you see your teammates or opponents exploit the new content/changes before mimicing the new meta, then you're already too far behind the curve. #adapt
And anyways, what's your problem? Does it hurt you to see one constructive/valuable thread for the community that is actively trying to help out? Or are you just really looking forward to toxic posts only?
You don't know any of the exact statistics of any of the new units or abilities. Therefore, making judgments about them based on partial information is pointless. Your build orders are based on what may be, not what is certain. It can go either way.
