I'm optimistic about the changes, but I still think that they need to change the GI, at least to high and low versions. I don't really care about the meter usage too much, because honestly, I don't think there is that much GI going on in a typical match to use up to 8 GIs in a round to deplete your meter completely. (not usually, anyway, unless the round turned into SC2 style GI volleyball)
But I already see this 'all-in-one' GIing becoming too easy. Take this example -- playing as Ivy, you try to be devious during a match which has been close by sitting on meter -- trying to maintain at least 125%. That way at the end of the final round, you get a free win by GIing ANYTHING your opponent puts out, and getting the free (seemingly, at this point) free CE afterward.
If you can still duck/jump it AFTER being GI'd, then hey, there's no problem. But if you CAN'T, I think it will be a big enough issue that it could help define tier lists. Those who get free CE after GI will have a big (unfair) advantage, especially with GI being braindead-easy
