I think this is a common thought of people, "This game is called clash of clans, so why is it the clans play so little in this game?"
While CC is the best defensive building, I think this game still need a lot of feature of clans to make it live up to its name, so here I have an idea for a feature of clan: Clan Barrack
So, here are the ideas:
1. Clan barrack is a new building. Similar to Clan Castle, it will not active if you aren't in a clan
2. Clan barrack has the same troops as Normal Barracks
3. Clan barrack does the exact same thing with normal barracks: making troops then troops go to army camps. It won't increase the number of troops that you can hold
4. You need to level your own Clan barrack to unlock troops. so, it will works like normal: you will need to be a TH7 to unlock Dragons
5. Your clan has a separate "troops level" than your own army.
Example: your archers are lv 3 while "your clan" troops are lv 5. If you create archers from normal barracks, they will be lv 3 archers, but if you create them in clan barracks, they will be lv 5.
Of course, your clan troops level is shared to all clan members, so a TH 5 can create lv 6 troops If the clan troops level are lv 6. Your normal lv 6 archer and Clan lv 6 archer has the exact same stats
6. This means Clan will have a 'laboratory' to upgrade clan troops. This 'laboratory' doesn't have a physical building, but rather is accessed from Clan info tab. And can only be used by Leader or Co-leader
7. Where's the resource's from? It will need a donate resource (Elixir) feature for Clan.
Note: Resource is only used for 'Clan laboratory', and can't be given back to members by any means
8. Troops upgrade price: I imagine it will be 10-30x more expensive than normal laboratory. After all, a clan can consist of 50 members
9. You might also have a way to 'upgrade clan' with gold, in a way that it will increase "max donation storage" of clan. An example of it with random numbers: A lv 1 clan has a vault of 1 mil gold/elixir storage. Lv 3 archer upgrade need 2 mil elixir, so before you can have clan archer lv 3, you will need a Lv 2 clan to increase the vault first.
That's the general idea. I have read the ruled out ideas, and I don't think This one is ruled out...
Idea no. 9 can be deleted if it's too complicated...
-It will increase troops cooking time, it will increase the game's activity
-Increase clan's benefit (and feature)
-Lower TH might be able to get a high level troops, but they will need to sacrifice cooking time because they can only use 1 barrack if they want all of their troops to be high leveled
-Will increase the 'strategical' value of clan: which troops to upgrade first?
I don't think it's too OP or too abusable, tell me what you guys think?
Note: Clan barrack might need higher resource to be upgraded because they are potentially stronger (or weaker. Depend on the Clan)
