Well, I've just levelled this, but haven't been to PvP with it yet. This is not meant to be a critique, nor am I speaking from experience. I'm trying to figure out which skills I might use. Perhaps you can comment as to whether I'm on the money, or not. This thread will be strictly from the POV of a cloaking / ganking, small scale, 2H / resto magblade, merely because that happens to be the first character I levelled the skill line on.
Time Stop
Doesn't really fit. The 4 second lead up to the CC of Time Freeze seems far too long, whereas the cast time of Borrowed Time seems more suited to group play, where you are not under immediate pressure. As everything is competing for bar space, I have to look at it as a possible replacement for Mass Hysteria. Nope. I don't think that's happening.
Elemental Weapon
10% more sustained damage spamming this against a target skeleton, and cheaper than Funnel. Definitely something to try. There are lots of possibilities with this. The guaranteed status effects trigger Skoria and will probably generate more proc chances for things like Sload. It's also kind of like warden birds in that there is a delay. The damage coincides with a light attack and, basically, with the subsequent skill cast. This might be exploited for generating burst. Healing from Funnel will be missed, though.
Accelerate
This is a frustrating skill. You can cast it and remain cloaked, so it seems to have been designed with NB in mind. But what do you get? Race Against Time might work on a stamblade. It's cheaper than Double Take, but that's about it. The extra crit damage fits with NB, but it's kind of a meh buff, and sprint cost reduction isn't really needed. Such a short duration. Then there is Channeled Acceleration. This can be cast between two Cloaks, while remaining invisible. You might use it in the leadup to a fight. The question is, is it worth it? The big stupid about this skill is that it slows you down during the channel. It is NOT an escape skill. Basically I feel that this competes with better skills, namely Double Take and Forward Momentum. Now if it was a magicka version of Forward Momentum we would have a totally different ballgame, because that's what I feel I really need. What makes me fast isn't Major Epedition. Well, it does, but snare / root immunity is more important. Not enough bar space and high opportunity costs for both morphs make this a crap skill, as far as I can see. Sprint cost reduction on a magicka build is nice - I've used the Prisoner set - but it's kind of down the list after break free and snare / root removal. With Concealed Weapon + Cloak it's basically only useful to a magblade, if you are marked.
Mend Wounds
I can see how this fits more healing into a GCD. Totally a healer skill, so that won't be me. Interestingly heavy attacks consume magicka.
Meditate
Exactly when will you have the luxury of using this on any build in PvP - or PvE for that matter? I don't get it. If you are that safe, you can just wait for your out-of-combat regen to catch up. My tooltips are about 1.5K / sec for each resource. My in combat mag / stam regen reads 1.5K / 600 right now, but
out-of-combat it's 2.5K / 1.2K (as displayed by Harven's addon). As NB you either disengage with cloak, and you don't need this, but if you channel this in someone's face you will not survive. I sometimes even die with Light's Champion active, although mainly if I leave it too late. I suppose there may be some tank build, maybe using Reactive, who can benefit from the Major Protection, but while that is strong, the resto ult and sets like Pirate Skeleton prove it makes you far from invulnerable. Maybe in conjunction with the 1H + S ult? By the way, do you know of anyone using the Shadow Walker set? What? You haven't heard of it? Yeah, that's because it's crap
. I hope I'm wrong, but compare it with Dark Deal. Now Dark Deal costs one resource, but the heal is about 3 times stronger, and the resource restored maybe 5 times, if memory serves (I don't play sorc, so correct me). Since Meditate doesn't cost anything, it should not match Dark Deal, but at the tooltips I am seeing it will be totally ineffective, I think.
Undo
Where were you 4 seconds before being CCd? I'm wondering whether to take the Precognition morph. The main attraction seems the position change, but I could be wrong. If a DK had you fossilized and beat on you, wouldn't it be better to break free, roll, take two steps, then use the ulti?
