For a counter offensive style, she is missing a crap load of aGIs. All her aGI option from SC2 back-stance are gone. I have 0 clue why it was removed, yet characters like Kilik/Sophy get them every game, even though they can zone perfectly while Talim need to be point blank. So many characters get aGI super, its a HUGE blow to Talim because there is literally nothing you can do about it. The string heavy nature of Talim makes it almost impossible not get hit by it, even throws get GIed from those supers (horror bad design). Even when you bait it, its still safe on block. If you try to bait it hard, the opponent can just backdash and use ranged options to poke you for free knowing you can't commit to anything.
I do think she could use ONE aGI from BT.
(Like her BT B+K from SC2, the other isn't needed, imo), She does have an aGI in Wind Fury stance (B+K) if you don't press anything. (It aGIs Horizontal Highs and Mids I believe), But that aGI is kind of iffy vs strings since she does a twirl away animation instead of the normal GI deflect.
The rest of what you wrote has nothing to do with Talim at all. It's more to do with the current design of the CEs in general. I personally hate that many CEs aren't more unsafe on block, but that is a separate discussion. If you're Talim, though, the counter-offense is about dodging as opposed to powering through stuff. The RE cancels are also very big in this sense, and I really believe when we get to lab this stuff that feature will make a lot of things more clear.
What is the reward you are talking about? High risk high reward require good mix ups. Good mix up are things like launcher / unbreakable tracking throw (aka what Ivy has). Even though both options are unsafe if blocked/ducked, they do massive damage + knockdown if they hit, and its a true 50/50 with no option select. Its even better when Ivy is near the edge, because she can RO you with a mid, so you pretty much has to eat the throw.
What mix up does Talim have? All her wind stance can be back-dash blocked, and punished if blocked. Those lows have no follow up anymore, just 25ish damage with +frame. I feel you are not playing real opponents who know how to play SC. Against online randoms, you can "pressure" with her strings+ stances. Against people who knows how to play SC and no lag, every one of those strings will get punished or put you in a extremely unfavorable position. Talim is absolutely not a viable pressure character, outside of lag + newbie. Her greatest tools in real tourney is just literally AA/BB/11KA/Throw, plus CH fishing. Occasionally 6B+K B/A mix up if you know your opponent is staying still. Compare to the amount of tools other character gained and universal changes to back-dash, I feel Talim is gonna get worse and worse as all the gimmick stuff get exposed.
If they want Talim to be viable while keeping the current "Style", then EVERYTHING she has need to be safe, like EVERYTHING. NONE of her moves give you advantage/special property/damage/mixup to justify being unsafe. Things like Stab/iGDR are unsafe because they are combination of fastest mids with the highest range and damage potential. Things like Kilik's Asura dance is unsafe because its a tech jump + mid GI + damage, the best move there is. Talim's moves do not have anywhere even close to 50% of their power, yet she is unsafe? WHY? Even if she is safe on everything she is still mid tier because range alone will kill her chance of being top, and she lack high damage lows/throws ... but as she stands now I see no future as a tournament character.
Once again, I agree with some of your points, then you go into tangents that don't really relate.
I agree she should get some more followups off her lows in stance. I think they played it a bit too safe with the reward for her stance lows, because her wind cannon is BIG damage. But yes, her WF A low doesn't really grant too much on NH. It's designed that way on purpose I believe. It DOES combo into FC 3BB on step counter though.
Windsault A is great on grounded hit, but standing hit doesn't give much advantage either. Still have to test what she gets off CH Windsault A. Online mode isn't the best place for that kind of thing. And I already mentioned in my earlier post that she's still a bit unsafe on things that she really needs, like her BT B and her 3B for instance.
We don't know ALL the frame data for her on block or transitions though. So that fact alone means we DON'T know how viable her pressure is.
We don't know how fast her empty WC or Windsault stances are.
We don't know how good her Guard damage is.
We don't know what setups she can use to counter opponent's strings. Maybe there's places to stick the B+K aGI and hit them with wind cannon.
Her anti Reversal Edge/GI game is silly.
Her RE cancels are powerful yet HIGHLY untested.
Her mobility can create whiffs better now than ever before. And I've been playing her for years.
I'm just saying, try to give some of this stuff more of a chance, especially her RE stuff, before you abandon ship.
