Having increased collision damage and having some cockpit shake and/or other effects (i.e. stopping both mechs, without anyone falling over) is fine. But having actual knockdowns can be...problematic. The problems are as follows, in no particular order of significance:
1. Adds even more fuel to the arm's race, because KDs are/were based primarily on tonnage -- bigger mechs got to stay standing after ramming into smaller mechs. There are too damn many people in heavies and assaults as it is. Let's not exasperate the issue.
2. Reduces the weaknesses in close quarters that long-range builds are supposed to have. For example, right now I have to try to take people out before they get within the min range of the PPCs on my Victor. If they get in there, my life gets a lot harder. But with knockdowns, I no longer have to fear people that get close to my meta Victor. I can slam into them at full speed and since I'm heavier than most mechs I'd remain standing. The other guy, however, would be an easy kill for me and would probably be dead before he gets up or at least crippled. He would almost certainly lose the fight.
3. Artillery strikes and airstrikes would be utterly ridiculous because you can just push someone over and then drop a 'strike on their face, and they would have zero hope of escaping. Best case scenario for your victim is that they would be heavily damaged. Worst case scenario would be the victim being instantly killed with pretty much no skill required on your part whatsoever.
4. Bad teammates would make life a pain in the ass while trying to maneuver around. For example, let's say I'm trying to poke around a corner to shoot the enemy, and a friendly Atlas or whatever thinks I'm sexy and begins to dryhump me furiously. I would fall over and probably get killed by enemy fire, due to my teammate's mistake. I should not be punished for
his lack of skill.
5. Further degrades the balance of chassis within the light and medium classes. Namely, the smaller lights like Lolcusts and Commandos can't really outrun the "good" lights like Jenners or Firestarters by a very large margin. They would be even more helpless than they are now. The same applies for the 55 ton mediums compared to the rest, but to a lesser extent than the light class. Slow lights would also be even more helpless against fast lights, because they have absolutely no way to kill another light before they close in for the tackle (unless the target is heavily damaged ahead of time).
6. Honestly, seeing gigantic armored war machines try to ram into each other at any possible opportunity just seems...awkward. There's a reason why modern militaries have decided to forgo swords in exchange for firearms.
7. I can't think of any more off the top of my head, but I'll be sure to edit more in if I do think of any.
