Hmm. I know Grysvok was powered up since 5.2 (IMO after Apharmd Striker, Grys was the weakest, though Grysvok Specialists can put up quite a fight in 5.2 ) but I don't know how tough Grysvok is now.
However, Specineff in 5.2 is a difficult VR to score hits on so I'm actually surprised that Specineff is having problems with Grysvok - unless they slowed him down considerably. How's Specineff's movement speed now? I know in 5.2 his standard walk is slow (rowing should be gone so no discussion in that line), but his dashes are very fast but very short.
Anyone tested out Specineff's side moving crouch speed? IIRC 5.2 Specineff has very good speed in a side moving crouch attack (Reminds me of playing Fei-Yen in VOOM: because Fei-Yen can't fire early in the dash, I used to go walking RW Handbeam < > moving crouch LW Bowgun-direction change to punish dash freeze) and should be able to evade all but the most homing attacks during his moving crouch. However, using moving crouch is definitely a lot easier with twinsticks than on the gamepad.
In 5.2 Specineff's crouch CW has decent homing (much better than regular standing); dash CW is largely useless, but forward-diagional dash crCW (forward dash crCW gives the sliding tackle) is quite effective but suffers dash freeze (which I gather is the problem: Grysvok's last projectiles will get Specineff during the freeze). Therefore, a well-timed moving crouch CW should be a decent compromise unless Grysvok's attacks are so homing a dash or jump cancel is the only way to evade.
If the stream of projectiles is considerable, I supposed a short dash-cancel should evade most of it, them a moving crouch CW to evade the last shots and counterattack.
Dordary, when played right, is very viable in 5.2 and I believe he has been powered up since: apart from (crouch)LTCW and jumping RTCW, most of his CW Flaming Rings (except his ram attack) attacks are a joke in 5.2 unless you time a CW just right to freeze your opponent. I remember I rarely had problems with Dordary until someone discovered the idea of keeping him crouched as much as possible (ground dash crouch attacks, moving crouch attacks, etc.) and cancelling dash freeze with crouch LTCW (a powerful stagger attack in 5.2), leading to all sorts of things bouncing off Tablehead (nickname for Dordy) most of the time because his already stupendous V. Armour is enhanced while crouching.
In 5.2 I've seen my Cypher's 4-Way Missiles bounce off crouching Dordary several times, and I heard a rumour than Temjin has serious problems vs a crouching Dordary because his RW is effectively useless most of the time (keep getting deflected by Tablehead), robbing Temjin of most of his damage potential. As in my FAQ, I modified my Apharmd Battler playstyle against Dordary to use mostly CW Sonic Rings and LW Bombs which can't be bounced off AFAIK so Apharmd Battler is not significantly impacted. I supposed that Grysvok's RW and CW attacks are liable to be deflected by V.Armour, and IIRC Dordary is faster than he looks (definitely a good deal faster than Raiden); Dordary can also use his forward dash LW/CW purely for movement / evasion instead of attempting to ram the opponent. IIRC, in the first Japan VOOT Tourney (I had a VCD record but it's damaged

), there were a fair numbers of machi Dordarys who made liberal use of his ram attacks to RUN AWAY!
Remember, all this is based on my 5.2 experience, so take this in with a mug of salt (and a lot of water too)!
