Seriously ND, you had us wait until you could patch in the ability to turn off Power Plays in the Lab, just to leave them in? Why on earth would you do that?
You keep telling us that the Lab is just meant to be a mode where you have fun so why ruin it with Power Plays? They kill the fun. Especially in Labs like the current one, where everybody has power weapons all the time. Being the Marked Man in this situation is miserable.
Your Power Plays really need some tweaks in general, but the problems with them are just worsened in the Lab. They start after six kills, which can happen in an instant, often causing the score difference to only be one or two by the time the Power Play actually starts. You can't even start to gain a lead without a Power Play ruining it.
On top of that once you've become Marked Man your stuck like that for the entire minute no matter how many times you get murdered instantly by 5 people with power weapons as their long gun and pistol.
You make us have to deal with these in TDM but the least you could do is remove them from the Lab so we can just enjoy the fun game type without constantly being worried about being Marked, Exposed, or that you're going to die in a single MAG bullet to your arm.
Also a side note: Although it's great that you don't allow kickbacks in a Power Weapon Lab, it would be nice if you could allow boosters as they create some more variety. Also you still have failed to remove the RPG on Airstrip. I guess you keep forgetting it's there but it is.
I could see both ways to this. I can't say though because I never touch the Lab.
I can't see any reason not to remove them.
And if you do touch the Lab, hope that you aren't Marked Man when everybody is running with an SAS and a MAG.
