Hear me out…
The problem that MPQ has, does not stem from individual character powers. It doesn’t stem from the overpowered nature of some of those powers either. In fact, it doesn’t stem from much except creativity?
What? Yes, creativity got MPQ in trouble here. How? Well, let me tell you.
Did Infiturn MNMags/Mystique exist before Mystique? NOPE
Did XF keep getting fed black before Iron Fist? NOPE
Did we have AP steal-a-rama before Hood and (new power) Loki were put on the same team? A BIT, BUT NOT AS MUCH
What about charged tiles? When did they become a problem? 4*THOR INTRODUCED THESE…
Hmm, I’m seeing a pattern here. New characters = new/improved powers = new combos. The problem is, they wanted to get creative with powers, so they had to introduce something. This maxes the game more complex, and therefore harder to control. It’s like a chemistry experiment where you just keep adding new chemicals haphazardly. The more you have, the more volatile the solution becomes.
Here’s a revelation. So long as they keep pumping out new characters, people will create more OP combos. It really doesn’t matter what the powers are, eventually the sheer amount of different powers will mean that one combo or another is OP. NO MATTER WHAT YOU DO.
What I think is that MPQ is shooting itself in the foot by continuing to pump out such a large amount of characters that they really CANNOT test all the potential overpowered combinations that people will ultimately find. I am sure people are already looking for the next HoodThorXF, and rest assured, it WILL be found.
This is the real problem. Nerfs and buffs are reactive changes that will never fix this sort of a problem. It is within the game already.
TL;DR: The real problem is that the number of characters = more powers = more combos. No matter what, someone will find and OP combo every time.
