Cool, I'm playing a different game again than most others \o/
Assuming the devs balance around dc AND idk, some changes really make sense imo. So let's enter my different game for a second and simulate as we all would play on the same server... Here we go...
A) Warlocks were stronger than every mage before the patch, but mages were better in every 6 man content, so I assume the nerf of both was reasonable
B) Some specific (very much) overpowered classes, such as Ch/B and Wl/S were nerfed additionally, perfect
C) S/M was nerfed aa few patches ago (lost 5% matt and got little xbow magic damage instead), the class feels like an average mdps these days to me. Nothing really broken, but equal to a bard/mage with just different advantages and disadvantages, but overall same damage.
D)
2) You take 10% dps from the mage, which is impossible to play in endgame instances (except m/s PS if someone decides to mention m/ch or m/r, then come to the dungeon and prove it to me in comparison with me). I will not even talk about the latest "boost" of m/p type connections. And we still remember "-26% intelligence". At the same time, such bundles as s/m, ch/b (mentioned by Noodlez), s/wl and the most juicy for a raid instance wl/d remain untouched. I still don't understand what you are balancing.
You could actually play M/K in there, which was rlly cool too. I'm curious if it's still viable, since I focused on op m/s and warlocks for the last weeks in dc. M/Ch has a shitty matt but is the very best mdps class in IDK imo. In DC it wasn't as bad, too and gave decent support to Ch/B (the same way a S/M supports B/M)...
E) I was testing the Wl/S on dummy yesterday and compared with my past parses. And (excluding the dummy circumstances) turned out it lost like 5.5% damage output overall. Damn, that's a huge impact! Wl/Ch didn't feel any change at all, the 5% feel like the normal variance while parsing (parses differ between +-2-5% normally).
F) Mages on the other hand, feel much weaker through the same 5% nerf. My M/S lost like 20% (should be less in real instance, would assume like 12-15%), M/Ch lost 11% compared to my parses from 3 days ago. So yea I agree, mages need a boost soon to be fine again.
