Well, i think we have to nuance our opinions anyway.
It's not like if we were facing a huge issue.
It's not like we're playing 40 shots rallies everytime either, far from it. It's just the expression of a frustration wich is mainly related to the 1.10 / 1.12 mod period, were we didn't decreased our speeds enough in time, it's coming better with 1.13, but can probably improve.
It's not either like cross accels "doesn't work", they work pretty well in 1.13, actually, probably better than with current MG settings (i played it the last 3 days), mostly on the strong wing side though, thanks to the average 85 consistency on this wing. Now it doesn't translates everytime to a winner or an opponent error, as our chars are also faster (thus have more acceleration as well).
The video of Ritchie/Cerji match @ Miami i posted today enlights this pretty well :

As the stats does. You'll see plenty of crisp cross winners from Federer FH side there, noticeably less from Djokovic probably, though some nice cross passings. This gameplay is pretty close from what we could observe @ US Open 2012 with 1.0e/1.08. Also the rally distribution is pretty nice with 76/46/38, on Cement (very slightly slower surface compared to US Open).
It think like Vmoe said attack/defense issues are subtle.
Currently it's pretty match-up dependant. As i wrote above, there's usually not much issues when at least one of the characters involved is one of the well powered 80/82 speed characters (Federer,Wawrinka,Haas, etc).
It is character match-up dependant, but also player level dependant. Meaning some issues may likely arise when an average attacker meets an average defender, or two very good defenders, especially when both players picked some of our fastest chars (wich are usually not the more powerful), and an average defender may still upset a good (but not strong enough) attacker, wich can be frustrating.
I guess we may probably reach a better balance when we'll decrease our speeds a bit more (2-3%).
Also something to consider, besides TE changes from 1.0e to 1.0f+, it that we also changed our Precisions stats after 1.11. Precisions on average were globally lowered in 1.12, wich doesn't help aggressive play either.
If you take Djokovic / Federer Match-up, for instance,
Wings precision/consistencies were :
1.08 Djokovic : +10 / +5 (consistencies 89/88)
1.13 Djokovic : +1 / 0 (consistencies 87/75)
1.08 Federer : +15 / +7 (consistencies 84/66)
1.13 Federer : +6 / -5 (consistencies 87/75)
So we'll see but i think that lowering our speeds a little bit more, and maybe restoring some precision on the strong wing sides may probably help to promote agressive game (remember of your Gasquet backhand with higher precision C4iLL ?), though i guess we don't want going too far with it either, to avoid seeing an overhelming number of winners on the lines, so trying reasonable positive values in between 1.08 and 1.13 values may be interesting.
