Much more optimized combos with pretty much no additional difficulty.
The meter-dump ones are kinda decent, but really Aquaman shouldn't be spending that much meter in a combo unless it's for SURE going to KILL the opponent (2nd lifebar). Much more useful to focus on 1-bar BnBs and save the rest of his meter for defense such as pushblock and especially clash.
There are easier to execute combos that do more damage and none of them were even mentioned. You'd rather call these "alternative combos for style if you get bored and are winning anyway". However, the video is nicely done, has notations and is edited well. Please keep making videos. Just make sure to find an appropriate title for them because this really isn't for beginners. At all.
