I get it that the way i worded this might be a bit confusing.

What I'm  saying is that why not add rares under the epics that are needed to fuse the lego champs......making it a bit easier to fuse the lego champs needed for the mythical fusion

That would be nice especially when you're only missing a few of the epics.  There is so many available now it's impossible to tell how long it'll take to get the last one you need.

Looks like they have been letting you earn some of the components in tourneys at least, the legendaries from wins and some of the other pieces from regular earnable rewards.

It's definitely a nice touch.  Now if I could only get then to drop the one I'm missing as a reward.

yeah they did a tatsu event but the tourny lasted a week, and by day 3 in the tourny first place went from me with about 5k points to someone else with like 20k points out of no where.

I guess I'm thinking about people who are more free to play such as myself, to make it a bit easier to get a mythical champ.

You would still need to farm or summon the rares, also it could help free to play/low spenders be able get a few more points in CvC events.
