Don't you think it's healthy for new players to read threads like these? I mean the last thing you want is a bunch of noobs who are upset because they thought HE gum was the solution to all their problems. It's good for them to understand that gum doesn't always work out, even if you spend five days and 130m on them.
It may be wise to say that it's not a significant enough increase in the drop rate to justify the cost of using them on "cheaper" items. Even if you double or triple the drop rate on cards, it's still statistically low that you'll find them. It's a risk versus reward scenario that does not pan out well unless you find a significant number of rares that sell for more then the cost of the gums that you've used. However, if you spent 500 mill on HE gums and found an MVP card using them, you've turned quite a profit.
So, it boils down to this simple principle: Don't waste HE gums trying to find things that you can buy regularly in player shops! It's better to save up for those gears or cards then risking money on gums that are not reliable. When you can start farming items worth billions, then go crazy with the gums!
Edit: ^That's what I was trying to say without having to do math, thank you!
