Id have to disagree, smokes biggest weakness is his wakup game, and what do you mean with his meter building because I think he is not a character that builds meter very well compared to others
Oh yea his wakeup game is his weakest
here's some specifics about Smoke:
8 Blocked Smoke Clouds = 1 Meter
28 Whiffed Smoke Clouds = 1 Meter
18 Air-Throws = 1 Meter
18 Whiffed Teleports = 1 Meter
Another important thing is that if you have like lets say 5% after his combo and he is expecting a wake-up he will Ex Smoke Bomb you. If you aren't blocking it's 10% and basically a free win to the round. If you do block its 2% chip and it stands you up. He might resort to this near the end of a fight. if you block it, even if you lose the round, at least he loses 1 meter.
1.) This is by far the best meter building string, its a 214 Smoke Cloud. it deals 5% chip which is great, and the pushback on the 4 makes the Smoke Cloud safe. It's a 3 hit combo and Smoke Cloud builds a crap load of meter on top of that. 3 of those is a full meter.
2.) 3D12 is his combo starter, it's safe on block Also, most Smoke's do not block after 3D12. It's a weird string, it doesn't look safe at ALL, but it is.
3.) B14 Smoke Towards / Away. he probably won't use this at all since it only does 4% chip, but it is unpunishable if he does it, as in nothing will catch him. Luckily every smoke player I've come across doesn't know this string, so you should be fine.
not to mention constant akuma teleport build meter
