Nothing wrong with Blitz as it is now. If, as the attacker, you don't set up with the risk of Blitz in mind then that's your own fault.
I can understand the frustration with Pitch Invasion, and it could maybe be limited to Placed Prone (or maybe Knocked Down with any AV break limited to Stunned) but I used to play when it was an injury roll, so I can live with a load of stuns rather than the deaths I used to suffer.
The Claw suggestion, while fluffy, is just awful, and would do nothing to "fix" the (incorrect) cries of "broken" - if anything, it would just make it worse.
Kinda wish i didn't even mention blitz, like i said i don't find it a massive issue, nice to have some debate about it though as many do, but think I'll have to concede on blitz.
As to pitch invasion i don't think its being better than is was is in debate, in that, it used to be injury rolls and now no longer, we all can agree on that, its like saying my venereal disease is better because it still stings when i pee but the rash has gone.
Not saying pitch invasion is a bad thing either, just i think limiting it wouldn't negatively effect gameplay or playerbase,. in fact you could argue it would improve it.
I don't want the claw idea to stop the crying of "broken" or "imba",. i want it to increase the chance of scoring more than the CPOMB team. Again in this thread, i don't want to stop the amount of killing CPOMB does, i want to increase the chance of winning a match against it by reducing CPOMB teams ball handling without effecting their agi in other areas
