Well i can only talk from a Mages perspective but i'm not really annoyed by movement on that toon. Why should i? casting scorch works perfectly fine, it can procc Hot streak so it never was that much of a dps loss (dont know lvl 100 numbers, but shouldnt be that bad), as Frost Mage i cant bother less with movement cause of 3 stacks ice floes, also thousand and thousands proccs of doom (Brainfreeze/FoF). Had about 3 Hours Garrosh Mythic wiping with a rnd group yesterday on my Mage first time playing that toon after 6.0 release in raid and i really never had a problem with movement, garrosh is not movement heavy, but shifting out for weapons etc was never a problem cause i just needed to pool for 1 stack of bf and fof and had not to worry about anything. On my warlock i have to place a about 2 RoF on different weapons (single target!!!-.-) each time i have to move for that god damn weapon, luckily i can port back in so only one walk of rain per weapon.
It relates in that point that i dont have a problem to be the last one on the charts as long as the delta is small enough (1%), to achieve that goal is again not what i'm paid for (and nothing i'm at this exact moment capable of). It relates to your claim, that buffing warlocks cast on move abilitys would just bring them back over the top what is the truth behind our claims for a better gameplay.
@wobblucy
sure, using the portal well is part of being a good warlock, but there are to many effects that prevent good use of our single best ability to relocate ourselves.
Take siegecrafter for instance
"oh you took time to place your portal? yeah well, someone pulled me so i'm just gonna remove all portals for good"
"oh you really choose a nice spot for your portal, to bad there's fire/sawblade/missile/whatever now"
.

in the end it is a portal, it can be placed beforehand but most bosses in suo tend to place funny things over wl ports to prevent their usage or force us to relocate them which is a huge dps loss (have to move to a usefull position, place it, move back) so in most cases there just is no portal
immerseus: sha-puddle
protectors: poison (but why would one need a portal here?)
amalgam: nothing \o/ (but most raids just reposition the whole group when the slicer comes close, so no use for the portal as slicer is not predictable -.-)
sha: yeah, perfect for prisions, indeed
galakras: what would i need a portal for here? maybe attacking the first mobs in the left tower, depends on tactic
juggernaut: nice for the knock back but theres a wall behind me, using one of my cast while moving casts while i'm on the fly should be more usef... oh wait .. nah better place a rain of fire
shamans: hey look a portal, lets place some purple crap over it
and so on .. i'm sure you all know the tactics for yourself
dont get me wrong
portal is a really nice little toy, in pvp its superior but in pve i would gladly exchange it with blink or even disengage
there are just far to much unpredictable things that render our portal useless or force us to relocate it from what was a perfect spot.
