First off, SPOILER WARNING.
Now, no offense, but how can one think that everyone in MTMTE has the same personality? Ultra Magnus? 'Witty and jokey'? I'd say he's quite the opposite. Would you say that Ratchet and Whirl have same personality? Cyclonus and Tailgate? Brainstorm and First Aid? Really? On the contrary, I see VERY distinct personality traits in each of the members of the cast in MTMTE, and not only that; the writers have made it a point to bring out those traits even more so than in the old ongoing series. As for RiD and the 'killing off' of characters/what was done with Prowl, well--I think issue 14 speaks for itself, eh? But seriously, I think it was obvious enough that there was something going on off-panel that linked all the seemingly 'pointless deaths' of the characters. They couldn't have just been random coincidences, and IDW doesn't just kill off important characters, if you take a look at the series and what they have done in the past, you would see that. Look at Ironhide, Sunstreaker, Rodimus, and Drift just to name a few--all of whom APPEARED to die but either didn't really die or were revived somehow. The characters who actually died and stayed dead (as far as we know) were not ever really major characters, like Ironfist, Rotorstorm, Wing, Blot, Flywheels etc.
So really--in the words of Prowl himself... 'How could you not SEE that?'
