Calculating tiles needed to charge a hero has always been painful for me: base speed, plus troops, plus costume, plus emblems, plus buffs… and some heroes reduce or slow your mana gain!
Yes, there are tons of guides on mana charge, but they require you to memorize tons of stuff, plus it’s still impossible to apply buffs/debuffs, and visually understand how many tiles needed to charge if the hero has more than 0 mana.
SG has all the data needed: Total tiles needed to charge, Current tiles charged, Charge per tile (buffs/debuffs) - why not show them in numbers? Who needs all these clunky “Slayer / Magic speed”? Show us mana in numbers please!
