What weak units?
It all depends on how you play. If you found it too easy, did you play on hard? I doubt you did.
The weak units are easy to make better. I, for one, found Micaiah's team (yeah, the "crappy" one), to be better than Ike's in the endgame.
You could give some units "adubant extra skills" to make them overpowered, or you could give them to someone else.
Play the game on hard, it will be a lot more fun.
On another note, I found some more interesting info on the Japanese site.
- Marth does not start at lvl 1 in chapter 1. Not having played the originals, I guess it could mean that there are prologue chapters included.
- Riff is in (which I believe he wasn't in the previous remake)
- WiFi is 2 players max, there is a time cap, and if I'm not incorrect, a move cap pr turn.
- You can see the range by pressing X (like pressing 1 in RD, I think)
- The weapon triangle is in. It wasn't in nr 1, and I don't think it was in 3.
3 arts (or whatever it's called), but I guess there's a lot more of them.

And the official boxart if anyone's interested.
