attack timer

Attack timer should be based of your army comps training time. and each troup trained more than 3 times the 4th one wont count .
Min time would be 30s if total troup trqined arr less than 30 mins
Each hour of is 1 min


Eg i had 1 hour of troup training time and 1h of spell brewing .i get 2 mins
If i ttained 240 gob id have 30 sec and so on.

This strategy will kill barch SQ and balance the game (according to sc) and will make attacks verry diverse


What do you guys think??

So how would you calculate troop training time?
Would it be total time each troop takes timed up
Or total barrack time ?
