I think once players found a good strategy that they can exploit to do contents in the shortest amount possible, and with the most safest strategy, we should keep it to ourselves. Embrava was amazing, it was incredibly useful on many things and not just endgame stuffs. But for a long time SE did not even care about it, for a long time there were not that many events where you absolutely need and must have to use Embrava and Perfect Defense, hence they leave it alone. So it is our duty to keep any great news about any jobs combination to ourselves
