So did Piggy's video tape solve the problem with Early game?

The delay in being granted the stall can realistically be the difference between undoing the progress the Survivors made and giving them a checkpoint that safeguards that progress (i.e. you can't regress a gen that's finished). You want to slow them down as soon as possible, and disincentivizing having Survivors immediately jump on the boxes runs contrary to that.

Not in the slightest. You have more guesswork in where they'll be at the start of the match because some COULD be at boxes others COULD still prioritise gens even if they 99 them. It's like a bad corrupt, because while it makes them act differently early, they could be anywhere on the whole map and still be progressing.

Then 2 minutes into the game, you're basically playing without a power. Traps no longer keep people off gens, traps no longer make people hesitant to pop gens, you literally just have the ability to move slower than survivors and SOMETIMES get a hit around specific loops.

It's an unreliable power at best, and taking away the stalling across the match makes it downright bad.

a streamer I was watching was doing what you talked about and this ended up happening

Reducing the top end of RBT stall does screw over the RBTs. Losing the potential to kill someone with them sucks too, but that's not the important thing about the Traps.
