The game modes are equal in all aspects EXCEPT PP, that's where the imbalance is, and that's all Sandro's proposal addresses, the imbalance in PP and it only gives modifications to the Powers, the players actually get no direct benefit from it, no extra credits, no extra merits, nothing.
Since Sandro said the data shows the imbalance, sorry, I'm going to take his word over both of yours that there is indeed an imbalance, especially given that you two aren't exactly unbiased in the PvE vs PvP bit. I could give a rat's ass to be honest, I did PP for a bit, it's a grind, pure and simple, and outside of the toys for certain Powers, pointless as far as I'm concerned. I could see the imbalance when I did PP, it was a well known fact, you two are both aware of this, ANYONE doing PP and reading the forums for PP and the reddits for PP are aware of this fact, it's not only known and discussed but it's openly exploited. This isn't something that Sandro JUST made up to please PvPers, it's been known by the community for a while, so why the ?
Again, imbalance in the modes regarding PP only, proposal from a dev to fix that imbalance, which is based on the actual game data. Strong opposition from the PvE only crowd...why? All modes are supposed to be equal in all regards, remember? You folks scream and rant about that all time, but when an imbalance is pointed out that does shows Open is getting less than it should, you say stuff it?
Funny, I know for a fact that if Sandro had said Solo was imbalanced and suggested a modifier for it, you folks would be screaming it from the mountaintops and demanding FD put it in RIGHT NOW! Guess that all modes being equal really does mean, all modes being equal but OUR chosen mode is more equal then the other....
