"Need"? No, this is a hobby... no one NEEDS anything.
As. Tomcat fan though, while there are kits that will always be "good enough" for me (the revell tomcat will always be a favorite for me. Good shape, easy to build, easy to modify), I will never not be excited about a new, more accurate and easier to build kit on the market (read: Tamiya).
I was initially just as excited about the AMK, until images of the real plastic started leaking, then instead of being transparent about listening to our concerns, they tried to deflect, saying "hey, look at our multi-piece wings!" Or "hey, look at our one-piece nose!" (A superfluous design choice, in most tomcat kits the nose halves go together without issue), or "hey, look at our multi-piece canopy!" (Another party foul, as was recently pointed out).
I want to be happy about this kit, but all AMK has done so far is succeeded at putting together an extremely expensive detail set I can part out on other, better shaped tomcat kits. They got so hung up on trying to make the most detailed kit that they could, that they forgot their fundamentals starting with the basic shape. I wish thet would have gotten ambitious and pooched a completely different design, because a tomcat with an accurate shape and and as much detail as AMK had boasted would have been impressive to see.
