Yes, versus Storm, Gief doesn’t want to be on point at all. That’s a counter pick scenario right there; if you want to run Gief versus a Storm team, you’ve got to set up a team that lets him DHC in and out safe. Unfortunately, every major team has Storm, so its def. an uphill battle. Gief/Storm/Sent can run with anything though, in any character order.
Zangief can run even with any of the tops, except Storm, her runaway game versus Gief’s inability to gain ground is a pointless fight-- she wins it easy every time. Best bet is to get bar and DHC in.
Versus Mag, Gief has an easier read, he knows its RTSD time, so you can block and guard cancel into SPD, or wakeup SPD, block into an assist pin setup with a SPD chance.
Versus Cable, same as anybody else, you’re just not allowed to make any mistakes when you’re on his horizontal, but he can’t chip you to death like Storm.
Versus Sent., he can chip you but that’s all his bar, so it’s no problem to sit and block. Sent’s so big that you can air SPD right through a lot of jumping normals, and just generally grab too much random stuff to even understand. Classic big character piledriver vacuum action.
I like Mag/Gief/Tron to start with, and if that gets shut down, you can counter pick a Storm or Cable or Sent depending on what you’re up against.
Mech Gief is fun sometimes. Kill a character in the corner, then Mech-up and layer a Tron plus LK Aerial Russian Slam. Right there Gief’s in prime position for his SPD/mixup game. IIRC Gief is not push-blockable because the ARS is basically an empty jump, so if they PB Tron, its land, tick, SPD. Standing LP is god-like as far as a jump-check, jumping LK too. Metal Gief is only worth it when you have another character that wants him as an assist though.
You’ve got to want him to get on point though-- he’s not that good an assist to warrant having him as an assist only character. IMO he’s got far more damage potential than CapCom or Psylocke. I’d even place Tron ahead of both of them-- bitch is too good, but harrrd to use right. Gief’s the same way, he rapes anybody that doesn’t learn to just run away. (At which point he just gets wrecked-- but if you can force run-away at will, then you can work around that with the rest of your team).
