Advice, you should use the small picture icons used in the main wiki's dialogue page, or at the very least fully type out the name of the characters every time with either a bold or italic setting to differentiate from the dialogue text.
The reason is that not only is it more visually pleasing and less confusing, but shows more effort and a sense of quality.
Amount the writing itself, it's very exposition heavy without a trace of character in Juggernaut. Juggernaut has a distinct personality and voice. Other than the mentioning of "Cyttork", there's nothing in his dialogue that fits his character.
You got the personality of Iron Man and Coulson right (although I would personally have removed the last "Mr. Stark", just seems like an overkill). I'm guessing that's because you're much more familiar with those characters because of the MCU and such.
First off, Duet was disappointing as hell. I won't spoil it if you haven't seen it, but the Music Meister is barely the same character.
I would have asked you this in chat, but you didn't show up today. I'm making a Luke Cage E-ISO, using "Always Forward, Never Backward" (from Luke Cage series) as the title. I initially came up with it thinking of using Lesson Learned but then I realized that would make his Street Cleaner E-ISO obsolete, so I can't do that...
Any other ideas for what I could do with that effect name, or should I try a new effect? I like the name but I need a good effect to match.
You got the most obvious reason correct, but there are a few others.
Unnecessary - The reason why those pages were created in the original wiki was because it was used as a guide for strategies. Since this wiki isn't about becoming the very best player in MAA, it would just be a waste of time.
Few Will Care - Again going back to the previous point, since there is no reason to conjure strategies by viewing the type pages no one will look.
Confusing - This wiki has several characters represented by a plethora of different creators. Listing the all the type abilities for all the Batmen in this wiki in a row will get convoluted.
Continuity - It works in the original MAA wiki because all those characters and gear exist in the same game. Many people in this wiki have there own vision of their fanfic MAA, resulting in them not viewing most fanfic in their world (an example is Bulk, though frankly he shouldn't belong anywhere).
