Every class complains about how OP another is. The truth is that every class is extremely lacking in areas that others excel in, which makes it so that out playing them is very hard depending on the situation. We need to return to D1 style subclasses that are more rounded out and can be specialized to a person's playstyle and situation instead if having cookie cutter subclasses that offer very limited variety and only excel in very specific areas. While D1 subclasses aren't going to happen, they could at least let us choose specific perks instead of locking us into perk sets. Subclasses lock you into a very specific playstyle that doesn't always fit the situation, and then when a different subclass perfectly fits the situation, you're stuck with very little opportunity to outplay them.
