Here’s the chart I made based on your original one, @FraVit93.
I also made one for defense. The defense one is in increments of 0.5 tiles because each tile that hits you on defense counts for “half a tile” of mana. → IMPORTANT NOTE… SEE EDIT BELOW
EDIT: I think it’s important to make a distinction with the defense chart. There are two ways you could look at “Tiles Needed” and it’s very important!
FIRST WAY:
Mana speed is almost always defined with respect to the amount of tiles needed to charge a hero’s special while on offense. The chart above is based on offense tile requirements. You’ve seen these numbers before. They are:
Very Slow: 13.5 tiles
Slow: 12 tiles
Average: 10 tiles
Fast: 8 tiles
Very Fast: 6.5 tiles
However, these numbers only apply to offense!
SECOND WAY:
When on defense, each tile that hits you counts as HALF A TILE worth of mana. If you account for that, the amount of tiles you actually need to charge a hero’s special looks like this:
Very Slow: 27 tiles
Slow: 24 tiles
Average: 20 tiles
Fast: 16 tiles
Very Fast: 13 tiles
That would make the defense chart above look like this:
Both ways have their merits. It just depends on what you’re trying to look at. Hopefully this isn’t too confusing…
