I remember supporting the above table due to its simplicity, but then I realized how the second table is much more applicable to all of the elements (Underworld included), even though it might be prone to some player error if they can't calculate their decks correctly/don't know how the rep system works. Mind if I give you an example to sort of figure the table out?
Suppose the following situations:
Time Elemental wins against an enemy player with the following decks:
-80% Time cards, 20% Other (Quantum pillars, shield, long sword, etc.)
-60% Time cards, 25% Gravity, 15% Light
-25% Time cards, 25% Gravity, 25% Light, 25% Entropy
-0% Time cards, 100% Other
How would the rep gains (and experience bonuses) would be represented for each of these deck archetypes?
