I mean I've never seen Deka, but the fact that episode featured Kruger fighting and Deka investigating made it feel worthwhile having them in the show. Kai at least was used to draw character moments out of the Gokaiger but the other three were certainly meritless and pointless - and that comes from a guy who LIKES Shinkenger. The worst offender was definitely the Gao cameo. Not only did GaoRed not actually serve any real purpose but that episode completely blew my mind, in a bad way, as to the shows continuity. I'd say the GekiRanger was worse for being so utterly forgettable but at least GekiRed was in the show so little he didn't have a chance to confuse the continuity quite like GaoRed and his Power Lion did.

I get what you're saying about Luka, it makes a lot of sense, but I would have liked to have seen more refined swordplay from Joe to give what Luka is doing context. But the best swordfighting stuff from Joe has come out of suit, I always find Gokai Blue largely blurs into the scenery aside form that one episode were he used every sword at once. In terms of suit actors, he is easily my least favourite beside Ahim.
