Assign Builders to reduce build time
Sorry if this idea has been posted previously but with 100 pages of ideas, it bound to be there somewhere.
When you've set an item/defence/offence to be built or upgraded, would it be possible to assign extra 'free' builders to the project to bring the time taken down but at a cost of resources.
For Example:
Clan Castle Level 4 > Level 5
coin Cost : 7,000,000
Time: 7 Days (168 hours)
(1 builder)
To add an extra builder it could cost 10% in the opposing 'easy' resource (gold <> Elixir) to reduce starting build time by 10%.
in this example:
Cost of extra builder: 700,000 Elixir
Time: 151.2 hours (6.3 days)
The 10% thresholds should be stackable/concurrent (100% - (10% + 10% + 10%) = 70%) instead of consecutive (((100% - 10%) - 10%) - 10%) = 72.9%)
With above example the timings and costs:
2 Builders : 7,000,000 Gold + 700,000 Elixir = 90% Build Time (151.2 hours / 6.3 days)
3 Builders : 7,000,000 Gold + 1,400,000 Elixir = 80% Build Time (134.4 hours / 5.6 days)
4 Builders : 7,000,000 Gold + 2,100,000 Elixir = 70% Build Time (117.6 hours / 4.9 days)
5 Builders : 7,000,000 Gold + 2,400,000 Elixir = 60% Build Time (100.8 hours / 4.2 days)
Likewise for training new recruits - if you have a spare builder or spare training house unused their 'tutor' could help the busiest training house by speeding up the training by 5% per spare training house.
i hope this request is well explained enough and popular enough for you, the developers to implement at the next big game update.
