What crutch classes should do:
-Allow new or low-skilled players to contribute to the team and be generally useful.
-Be limited enough that new players move on to the next class once they feel more comfortable with the game.
What crutch classes actually do in ME3 MP:
-Make the game significantly easier no matter what skill level you are at.
-Trivialize all other classes into "I'm gonna handicap myself for the funsies" classes.
If crutch classes worked like the first example, I would have no problem with them. The problem is, they actually act like the latter. So I am forced to choose between limiting myself to about 1/4 of all the classes, or purposely gimping myself just to experience a wider variety of playstyles. The fun of mastering a class is greatly decreased by the enduring truth that I could better my performance by simply abandoning the class for a more effective one.
And I'll drop another link to the "why balance is important" thread:
