Believix, Speedix, Tracix, Zoomix, Sophix, Lovix! are these ALL necessary?!?!

Wow! 6 tranformations in one bundle?! is that REALLY necessary? Believix is enough, isn't it?!?! but they need a speed, a transport, a tracing, a summer AND a winter?!? Please comment to this saying if you think these are ALL necessary!
