HCamp training is becoming (has become?) a force in the game. In arena, if I'm looking to attack someone, I can roughly tell how much training they have by their power (assuming typical meta, 105s). However, there are so many places where it would be very nice to have some way to see how much training a hero has. This would be very useful in WoG, to see that someone isn't just putting up an ER, but a 100% trained ER. It would also help to determine, why did I roll/get kicked in that last battle.
Here's the idea:
I think it would be enough to have a rough percentage of the "big" stat for each hero visible on the hero icon. I was thinking about a thin vertical line along the right edge of the hero. It would represent the percent amount of the "big" stat that hero has compared to level 45 max amount.
Thus, for an HP hero trained at 11,000 HP, you'd show a half-height bar.
Like much of HC, you wouldn't be able to tell exact values, but even telling a rough % of the "big" stat would tell you roughly how tough a team is. I'm thinking of only the "big" stat (HP, MagPow, AttDmg) because a) every hero has one, and b) while it might be nice to know the amount of phyCrit or magCrit or armor or something, they all too often get filled long before the "big" amount.
I think putting a % number is just too big/unnecessary to help us visually see how powerful a hero already is.
We already have edge color, legendary status, stars, and corner statuses to help us see the power of a hero. Why not training?
