Honestly, it seems functional if underwhelming. It has the misfortune of being tier 8 and being compared to the Ramka, Termi 2k, and Termi 2017 which completely wipe the floor with any and all missile TDs of the tier. Disregarding the termis, comparing the other tier 8 missile TDs (except the trashsat):
TL;DR: the M1134 is kinda bad, the VCAC is OK, the Khrizantema is a bit meh
The more I look at it, the more the Khrizantema looks like a knock-off VCAC. Yes, it gets some of the features of the VCAC (in some combinations that the VCAC can't get), but as far as we know it doesn't get a lot of the other features that the VCAC can (360 smoke, hard-kill APS, no camo penalty for moving or reduced penalty for firing, auto-homing). It's like someone decided that the VCAC could get better vision control and both options of the top firepower choice (HOT-3s and double-shot) as long as it sacrificed the 360 smoke, auto-homing and all of options for the 2nd-highest choices (hard-kill, moving/firing camo penalty reduction). Personally, that's not exactly something I would consider to be a fair trade since I generally avoid double-shot and almost exclusively used the HOT-2MPs on the VCAC (yes, even after 0.33, fight me). Unless the Khrizantema gets some really interesting overprogression upgrades (I suspect that the double-shot will be one of these) I can really only see myself saying "meh" and playing something else.
