This is low effort bait. FFXIV's combat is slower paced so the longer GCD makes sense there.
I'm really tired of all patch 8.2 discussion being plagued by FFXIV talk, and this is coming from someone who likes the FF MMOs. Competition is good for the industry and I'm glad both playerbases have something new and exciting to look forward to. Neither product is in any danger of wounding the other so I really don't understand the basis for the hostility.
Or did everyone finally get so sick of crapping all over their own game that they now have to crap on someone else's?
