It’s a PVP game.
In a PvP game, one that’s respectable, one expects the same unit to behave the exact same way with the exact same outcomes if the same operations are performed under the same circumstances.
Same plane. Same initial conditions. Same inputs (within acceptable variance as demonstrated by the graphs).
VASTLY different outcomes.
Difference?
Either 400 golden eagles (roughly gives 4.5K skill points, as the plane already had little under 1K invested) or … we’ve got roughly 712 crew XP invested and need 5142 total, so 4430. Or 443 000 RP.
443 000 RP, 2200 RP per 15 minutes assuming perfect gameplay - 50 hours.
50 hours until the two planes are at parity or 500 golden eagles.
Can you look at someone straight in the face and claim having the ability to sustain 5.5G indefinitely versus someone who is yet to use that very aircraft for 50 hours and thus passes out after 21 seconds is NOT a massive advantage?
Because of crew skills, my F4U-4 technically turns better than all my turnfighters because my turnfighters pass out before they get lead on target.
In a PvP game, paying money should be about unlocking NEW EXCLUSIVE units to use in a roster (ergo - “DLC model” like AOE2:DE practices) and making it faster to obtain new units significantly (League of legends model) and cosmetics (that do not impact glance value). Units themselves should have no variance between whoever uses them outside of the user’s skill.
