Why would anyone do this? That's just a bit silly isn't it. People like their one champ defenses in Classic, like it in Tag. No one is forcing anyone to do any of that, people do it so they can farm quicker. Many in G4 Tag do not at all.
I'm like 60/40 fall/hold. Most weeks, like last week, I fall all the way to zero then push back up to 1200 on Sunday in about an hour on and off. Kind of my favorite way to stay in G4 since I only have to play when I have a window I can set aside for it.
But seriously why would ANYONE want this full team all week nonsense? What does it prove about it being broken or not? Nothing. You know what's broken? An arena mode with a 20 loss limit per week like Classic has.
At least I honestly earn my zero points that I climb back up from when I choose to fall. People beat me with 1 champ defense, I lose from Monday to Sunday. Push back with a page or two of one champs then full teams for a couple pages. Classic is free rank with a hidden boost every single week.
Many weeks, a little less than half, I keep my full team in, and I just stay at 1200, if I've got a busy weekend or week. Then I just have to play a few quick matches every other day or so and stay in G4.
And since you're asking me what I find fine, let me be real with you. I think if you can't stay in G4 Tag with very little effort, it means that you're not good at arena, and the skill/win based matchmaking in Live and the joke that is Classic Arena has convinced you that you're way better at PvP than you actually are. Improve your builds and your teams and you can hang.
I'm looking at you @dthorne04 . One day with a little more PvP effort you can come permanently hang with me too. I know I gave you my builds, so it's time my friend. :)
