I don't think so. Doesn't seem to have any stances so that does lower the amount of moves he can use. But SC hasn't been known to have huge move lists to begin with.
If 6B?, litttle pommel tap, into Ingi is a punish I think his punish game will be fine.
But on that note; Is Igni punishable on hit? If so, how bad will it be on block? I think we will be using Igni in combos with Quen and Aard being our stance mixup.
Have we seen and of his Lethal Hits?

Post all your Geralt videos here, whether they be Combo videos or just fun fan made videos.
