OP, here is why gunblade is no longer viable.

Kat's only spammable AD, W, has a pathetic AD ratio based on BONUS AD, not total, and an even lower ratio based on AP. Gunblade will often be the only AD item you buy on Kat, and it has a mere 40 AD bonus. Here's the calculations:

60% x 40 (AD from GB) = 25 bonus damage.

15% x 70 (AP from GB) = 10.5

Now compare to an AP item of comparable cost, Rabadon's Deathcap.

15% x 196 (total AP of Cap alone) = 29.4 So you get slightly less damage on one ability but much better damage on Shunpo and Bouncing Blades.

If you want to argue for the active, I'd say just getting a Rylai's is better. You get tankiness, more AP, and a slow that procs every 4 seconds on her W, keeps a whole enemy team in her Death Lotus AoE longer, and makes chasing with Shunpo MUCH easier since Shunpo is a single target spell.
