That's asking people to relearn almost everything this late in the game's lifespan, throw out every single BnB and start over. Makes perfect sense for SG2 when everything's gonna be all new anyway, but I just can't get behind such a massive change to SG1 now. It's way too much too late.
With how the cast has been carefully balanced around their damage output and how many resets it typically takes to kill, couldn't this have some deeper repercussions as it'd likely nerf some characters harder than others? You would probably have to go back and rebalance practically the whole game around this, adjust the numbers on everything. I thought beta was supposed to be done very soon, but I would expect this to delay things much much longer to make sure you get it right. And I don't think you can have that be the final patch either, if you shake up the entire game this drastically I highly doubt it could be perfect on the first try. Would almost certainly have to give it time, see what it does to the meta, and then do another round of balancing in another year or so.
