improvements costs discrepancies
hi,
I've never really been interested in improvements, the ratio cost/bonus not being in favor of players. anyway, i had a discount at the wheel of fortune and decided to take a closer look at them, and came up with this wonder: why 2 items with the exact defense bonus, don't cost the same?
an example off the top of my head: the vyeon's shield costs 90 sapphires, for +10 bonus. 5 of them will cost you 450 sapphires, for a bonus of 50. which is the same bonus as the hydra, for instance. only hydra costs 1000 sapphires.
now you could argue hydra has extra feature (the 2 hour automatic reanimation, pretty lousy one, to me) so i'll take another example: the guard cohort costs 300 sapphires, for a bonus of +20, which is the bonus of a shade's pavilion, for a cost of 200 sapphires. both being improvements without any kind of extra features...
so i'm curious: what does justify those discrepancies?
