have you ever encounter during your elementary school days problem like this...

if worker A can finish the job in 10 days, while worker B in 8 days.. with the workforce combined.. how long would it take to finish the job?

with the formula (typical elementary days challenge)...

T/10 + T/8 = 1

where: T/10, T/8 = time it take for worker A and B to finish the job respectively, and 1= the Work itself
solving for equation


T/10 + T/8 = 1

....(4T + 5T)/40 = 1
....4T + 5T = 40
...9T = 40
...T = 40/9 = 4.44 days

both worker A and B can finish the jon in 4.44 days...


NOW.. APPLYING the formula to Clash of Clans

IF Builder A can finish the job in 14days. Builder B in 14 days, and builder C in 14days

How long would it take for the 3 of them to upgrade the Townhall?

IDEA 1: builders UNION
...
before upgrade.. ask how many available workers you want to use..
pros: avoid idle builder, more time to loot, and shortens build time



IDEA 2: Special PENETRATING REVENGE(cooldown, 1day)
...
Every day.. you can get to Revenge 1 user even if He Has a Shield...
however,, if during the same day.. if 3 players already used the penetrating revenge to the shielded user, you cannot attack him/her anymore

IDEA 3: Unlock level 4 Pekka on TH 9 -.- and disable the clan newbie in seeing where the bomb and traps are during preparation day.. lots of Spy on Clan level 5+ -.-
