#1 is no biggie as I'm more about the fighter mode anyways.
#2 I already knew about from the previous pictures, again, not a big deal to me.
#3 Also not a big deal, it doesn't sound like anything my hot glue gun can't fix.
#4 -See my answer on #1.
Fighter mode being tight and staying that way even after multiple transformations is what I like to hear! It sounds like this is gonna be an awesome Valk and makes me glad that I've got one coming my way.
