Honestly I'd say don't bother with conq till reworks. I've been maining him since launch, played in loads of battlefly tournaments with him and got top 4 about 8 times. From a 1v1 point conq has an extremely limited kit. If you are the type of guy that can't be bothered to turtle and can't parry everything on reaction you will struggle a lot with conq in a lot of matchups.
If you still want some juice here you go:
You can full block feint any attack into a guardbreak with proper timing.
Front shield bash gives you a guaranteed heavy on any assassin, it's also guaranteed against regular guard if your stance wasn't matching their before you bash.
You can charge a heavy and get a free gb of blocking any light/heavy attack. You can also cgb during this but you have to cgb before their gb connects with you.
