Edit: That's also why people are trying to convince Trion to rethink the scaling of the Mega Damage buff from the red orbs in warfronts.
AP scaling needs to be fixed, not the damage buff. People can't go on stacking crit forever. You can't have T5 content with people sitting at the same base damage they had in T3 content, but now with 50-60% crit chance to make up for it.
They've backed themselves into a corner on that one. When the rogue changes for 1.2 were on the test shard and for some time after they went live, the complaining from rogues that the Backstab change was a nerf (when in reality, it was a buff) was fairly constant. The only way for them to change AP scaling now would be to go back and nerf the damage modifiers on all of our abilities, and trying to sell Joe Average on a tooltip nerf that winds up being a buff when you factor in changes to AP scaling would be pretty rough.
What they end up doing in the long run I can't predict, but what I would expect rather than changing AP scaling would be to change crit scaling and then adjust itemization in future tiers of gear to boost base damage without running crit through the roof. (Or just itemize for AP without ratcheting up the Dexterity.)
From a "progression is fun" standpoint, my issue right now is that I can upgrade the **** out of my gear but the actual increase in performance doesn't really seem all that substantial. I hit prestige rank 2 on my rogue and equipped my rank 2 PvP gear (which in many cases represented an upgrade from mid-40s greens to T1-equivalent epics) and the end result in my damage was ho-hum for the most part. I need another 10k rep with the Codex faction to upgrade my weapons but even then, the translation from upgraded weapons -> on-screen damage isn't that significant.
