No MMs or PBs please.
Why no MMs/stalkers/PBs on speed runs? While I have no doubt that some players will have toons of these ATs which are capable of contributing to a speed run, it has been my experience that the opposite is true.
Most MMs/stalkers/PBs either spend most of the TF on the floor or not hitting what needs to be hit fast enough or with the necessary amount of damage.
If your favourite toon is one of these ATs please do not take offence. There are many other things in the game that I am sure you can do very well but helping a team to get an excellent time in a speed run is, in my opinion, not one of them.
