SplinterGuide rating methodology updates - May 13 | Splinterlands | Ecency

Here are the updates we've recently made to the ratings on SplinterGuide. If you have any feedback, please leave it in the comments!

Miscellaneous updates

Remove -0.5 penalty for not having attacks: This is to take into account that having no attacks is sometimes a feature (can't kill themselves due to reflected damage) and also to reflect the addition of Weapons Training to the game.

Ability score & synergy updates

Increase Rust ability ratings (6 --> 7): This was done to account for the fact that Armor is very much still in the meta, therefore giving Rust a lot of value.
Inspire + Rust (medium synergy): Both of these together are particularly helpful in no-magic battles.
Heal + Scavenger (medium synergy): This synergy really just targets Gelatinous Cube, but is well deserved given that units with Scavenger gain health over the course of the match and therefore self-heal higher amounts.
Magic Reflect + Void (low synergy): Remember that "low" doesn't mean bad, it just means "small bonus" (rather than large one).
Added a multiplier based on health for units with self-heal: The higher the health, the higher the self-heal.
Increase repair ability score multiplier from 1.25 -> 1.4

Stat calculation updates
What we noticed is that monsters with very high damage stats (e.g. 4+) were often underrated. So we changed the formula to be non-linear. This effectively gives a small reduction for cards with 1 melee/ranged/magic and slightly higher ratings for 2+. The biggest boosts are for cards with 4+ on their attack stats.

Melee stat formula updated from 2.5 * {melee} --> {melee} * 1.8^(1+{melee} * 0.2)
Ranged stat formula updated from 2.5 * {ranged} --> {ranged} * 1.8^(1+{ranged} * 0.2)
Magic stat formula updated from 3.5 * {magic} --> {magic} * 2.25^(1+{magic} * 0.2)
