Two Deirdres: Merge or give Quick Riposte off?

Save Spd Ploy for Arvis.

I'd personally say merge them or save Speed Ploy for something. There's no significant difference between QR 2 and 3.

Unless you want to fodder off Spd Ploy, just merge them. Quick Riposte 2 works fine enough unless you're really itching for those Arena points.
