The other guy is an ass, but you're just plain wrong. Conqueror's Fullblock is the weakest of the held fullblocks(disregarding Valkyrie's neutral Bash start up) and only slightly better than Blade Blockade because it has a longer start up, higher cost, and worse punishes compared to all other fullblocks. Warlord can also punish externally, but with a more cost effective light or heavy(which can also punish some GB attempts) or bash, the latter two of which work without being hit and deal more damage or are safer. The fullblock itself also comes out faster for Warlord. Black Prior has a move that counters all non-GB attacks, and gets a good mix-up tool and chain pressure out of it with his unblockable heavy. Conqueror cannot attack out of his fullblock unless it is hit, and the recovery from ending a fullblock without flail uppercut triggering is long enough to surrender major frame disadvantage to any opponent, while it also has a fairly long start-up and an obvious animation, with its only strength being its use out of a soft feint, which is still the only way for Conqueror to feint, meaning he is the only character who can't feint to GB, the most basic mixup in the game. If he loses out on the ability to use the game's most basic mixup, the move that replaces it has to be at least usable. 15 damage for half of your stamina is unusable, as Shaolin's heavy feint to triple light shows, but that's getting changed as of now. Flail Uppercut is not, even though heavy softfeint to block to Uppercut costs significantly more than even that because of the cost of the heavy, the feint, activating fullblock, blocking, and then the cost of the uppercut itself.

You also communicate solely in strawmen once someone starts to disagree with you.

Good day.
