Supercell may decide this counts as clans pooling resources, which they have ruled out.
The problem now is donating is challenging for those who don't have time. This is an exchange of resources, which in effect, is the same as it is now. It's just more efficient.
This is easily abusable. Right now I have my TH8 completely done except for walls, so I can spend the day filling the CCC with 12 dragons every 90 minutes. And that's just me. 50 people would have 600 dragons stored in 90 minutes.
That's a good thing, if a player has a 8-5 job (who has money to spend on this game) that needs donations but don't have time all day in chat to donate, he can queue up the donations and focus on attacking.
Also, if I can shop for my troops the Clan Castle loses its element of randomness. Might as well just make the troops yourself.
Right now it's not random, unless you want your clan to be random, my clan you can request anything and get exactly that. Not quite random.
Low-level troop donations wouldn't be welcomed, or used. That means newer players won't donate, and won't be in the habit of donating when they become high-level players. Worse, the CCC would fill up with troops no one wanted.
Low level troops are for low level clans, as the player moves up, he can switch as he chooses, or grow along w/ the clan.
Still, be careful when changing the game. The text box for donations has been an ordeal to manage. People demand specific troops or specific levels, which inadvertently excludes some of our newer players. When they say "lvl 4 plz" half my clan can't donate now, which is stressful because we have a minimum. So I don't let my clan members demand by level.
If I'm donating level 4 troops, I'd hate to get level 2 troops, if people are fine with that, then settings can be made.. I prefer to receive level 4+ troops if I'm donating level 4 troops.
