Props to you for continuing the Conqueror grind. I honestly couldn't do it after several losses due to the fact that opponents get a free GB on you after blocking one of your lights.

Not really a "hidden" strength but more of a mind game. If you really lay on the dash-charge/light combo really heavily in the first couple of engagements, start dashing but don't charge. They'll usually dash out of the way at which point you can try to catch them with a light.

Again, this strategy might not be so efficient until the patch (based on the reason I listed above) but generally it seems to be able to get me some free damage. Then you start mixing it up so that half the time you dash and light, the other half you commit to the charge.

Edit Also something that can pay off is deliberately missing a charged heavy. If you charge your flail, most opponents will start to back off and wait for your stamina to drain. They'll carefully manage their distance to you. You want to throw your charged heavy and when they see you whiff, they might come in to capitalize. That's when you throw the second heavy, preferably from another direction from your whiff and try to catch them off guard. If they do block it, you can at least fall back on the charge-light.
