My first curt response from Scaredgirl o_O
With a low rating you'll make ~90g per pvp win, compared to ~15g per elder win. Later on pvp will average out to 50g per win. The issue isn't so much speed, it's skill and the luck of the draw. I wouldn't recommend a noob jump right in to pvp, but if you're starting a second account, or reseting like I did then playing pvp is a good choice.
You can't just compare how much Electrum you get from a win and base the speed on that. You have to also take into consideration TIME and extra cards won.
Here is the formula:
Effectiveness of grinding =
money and cards earned divided by
time spentI can guarantee you that grinding PvP is slower than AI3. Anyone can test this themselves by doing both for an hour and seeing how much money they made.
Waiting for the opponent to make his/her move makes PvP insanely slow compared to playing against AI. In the time it takes you to win
one match in PvP, you would probably win 4-5 against AI3 with a mono-speed deck. That means a lot more cards won, which means tons of more money won.
Also in PvP you will actually
lose games. Against AI3 (with the right deck) you won't.
My goal with this thread was to show how newbies can make money
fast, and grinding PvP is not a good option if you want to do that. It might be more fun but not faster.
