G'Nite! :D
 * 1) Because if your brain processes the information, but the armor you're wearing is too heavy, you don't have the speed necessary to react. That's just common sense imo. :/ Also, you're making the assumption that Ikaruga was going at top speed when she and Erza clashed, which isn't necessarily the case. She did clash with Erza earlier in their fight in just the same way without using any noteworthy speed after all.
 * 2) Yeah... no. Mashima has not explained his world in near enough detail for you to try to debunk the artificial eye, lol. You say that the eye can't realize the light was Magically affected, but why not? Who are you to say whether there's a difference between magically refracted light and regular light? And if it sees through magically refracted light, then it doesn't change anything. It just sees what's actually there. To you, it's just as believable. To me, the eye is believable and the ocean shit... is shit. :/ Again, its all in the eye of the beholder (no pun intended).
 * 3) But... you mentioned it. ^___^ Which is why it's a part of the conversation in the first place. And when you have an ending as bad as the sixth sense shit, do you honestly expect anyone to be upset about the Nakama speech? :/
