Yeah, the terms can confuse me alittle too, but they just sound complicated when they really aren't.
But anyways....
I could see a clear difference in your playstyle when you were in the lead, compared to when I was in the lead. You got alot more "aggressive" when I was in the lead, which isn't good. Ike (and most other heavyweights) are not supposed to be very aggresive at all, as an Ike player you're better off trying to punish your opponents misstake, or bait them, you also have to read them and get punish.
Punish: You punish your opponent with a grab, an attack or something els when you get an opening because they screwed up in some way (they used a slow move etc. etc.)
Read: I predict you doing an action and then punish you for it.
I think that you're going to jump so I do an up-air attack to punish you.
