Display MoreFrom JamesBond79 post it seem that the cost in crystal and gold for upgrading the hoplite attack is exponential, doubling each up
while the increase in time seems linear ( 3h, 4h, 5h)
This should mitigate the fact that ups are infinite.
For example try to calculate how many crystal and gold is needed to up an hoplite a total of +200 attack.
If they double, everything stops at around lv 20 when it costs 2mil for 99.9% of players and not even whales would do lv 30
But I already saw somebody with lv 30 spearman so I don't think it doubles.
