Alrighty, just read 35 pages of qq, about to chime in myself.
First off, I'm predominantly a pvper, and know more about that, and a sage (ftw), and know more about that. I run a dps 0-23-18 tk/balance hybrid, just to throw that out there.
To pve'rs saying things along the lines off "Oh Em Geee BW y u nerf pve 4 pvp whinerz??" and don't give a specific reason, i have no time for you. I also pve and these don't seem like a big deal, but I'm no expert.
My thoughts on various sage changes for pvp:
-Force wave change from 360 animation lag KB to 120 degree kb: honestly, this sucks, why limit it at all? Nobody complains, its a moderate kb at best, and trust me, I fully intend to hit everyone in that 360 radius.
-force stun now a 10m range: mixed feelings here, mostly about huttball. While the fear of being stunned in the fire by a faraway sorc is lessened, I can't do that anymore either, which blows, that and force wave were my two tools for fire kills, and they are pretty much both gone.
-force speed now 20s cd: great, and if it stacks with TK effusion, better! I would take that anyways for obvious force conservation reasons. However, I was reading this thread, and somewhere I spotted someone say that shadows might have the capability to spec into a 5s cd on force speed. That combined with resilience just screams oh my God for huttball. Seriously just think about that for a second.
-force mend and its specced talent for more healing: great, 30s cd, I'll just chuck that up on cd I suppose. It just really angers me that instead of a dedicated cd for a flat damage reduction over a fixed time period, we get this "moderate" heal. Very disappointing with the absence of a dedicated defensive cooldown.
-Kinetic collapse cc now no longer breaks on dmg: great, love it, no longer worthless resolve filler.
-mental alacrity change: don't care, don't use it
-"Fadeout/Egress has been redesigned. Now causes Force Speed to remove all roots and snares and grant immunity to roots and snares for the duration." when I first read this, I was ecstatic. Beyond happy. Everything I was dreaming for in this patch, finally, thank God, immunity from cc during the duration of force speed. But wait, what's that? Its a healing specced talent? When I got over the initial "removes all roots and snares..." and read that, I was furious. Dps sages are the worst dps class in rwz comps by far; so many times have I wanted to take my main, my dps sage, into rateds, and been asked to take my guardian tank in much worse gear instead. Compared to other healers, seer sages perform excellently given a skilled player, but dps sages get focused and demolished by players of equal skill and gear, and it just angered me that the very best buff the sages got was to healers.
If I made some mistake or left something out, I just read 35 fing pages and I'm not checking.
oh and force wave change sucks
