"Goblin LORD" :
If you want an ORIGINAL really great idea, spend the next five minutes to read and understand this one!
Now, I know SC already eliminated the option of a new hero, so let explain my idea.
-We add 50 more single player maps.
-Once you beat all 100, you "unlock" the "Goblin Lord". But he's not like any other of the "regular" heros.
He can only be used when:
- Attacking the Goblin Single Player Missions
- Attacking in multiplayer (He costs 100K gold to "bribe him" to come each battle-- He "costs" 1000 Gold each second after he is deployed-- he costs less gold as he is upgraded).

... 3. Defending against the Goblins.
Here's my thinking: SC created that game so that when it first starts, during the tutorial, 3 measly goblins attack your cannon.
They steal no loot or anything... but yet we go through 50 single player missions trying to get revenge?
This has never made sense to me, so here is what we could do:
The "Goblins" will attack your village at random, once a day. (The Goblins are computer generated (CPU's), and not an actual player).
Your Goblin king will defend your village from the goblins when they attack. NOTE: He will not defend your village against a regular attack.
By clicking on the name of computer-generated player that attacked you, you can "visit" the base, or "revenge it." (This will appear as a new tab next to your defense log).
If you revenge the Goblins, you will see their base. The base will be one of the single player maps. Except it will have ALL LOOT AVAILABLE, as if you hadn't ever stolen any of it.
Here's how it works:
Say you just started the game, and you beat the first ten missions in single player. Once you get in Bronze league, one of the first ten single-player maps will attack you typically once a day. You can revenge the goblin map that attacked you, and steal all the loot as if you never had attacked them before.
Then lets say you beat the next ten maps, but you're still in Bronze, only the first ten maps can attack you until you reach Silver league.
While you're in...
BRONZE: The 1st 10 maps can attack u, & u can revenge & steal all the loot available.
While you're in...
SILVER: Maps 11-20 can attack you, & u can revenge and steal all the loot available.
While you're in...
GOLD: Maps 21-40 can attack you, & u can revenge and steal all the loot available.
While you're in...
CRYSTAL: Maps 41-60 can attack you, & u can revenge & steal all the loot available.
While you're in...
MASTER: Maps 61- 80 can attack you, & u can revenge and steal all the loot available.
And while you're in...
CHAMPIONS: Maps 81-100 can attack u, & u can revenge & steal all the loot available.
This way, players will want to rise in cups in hopes of being attacked by the goblins, and stealing more loot when you revenge.
In Champion league, single player map: 80-100 can raid you. This means that if you are in the champion league, once-a-day, you will be attacked by "The Goblins".
They can steal 5% of what's in storages. 0% of what's in mines/pumps.
If you successfully 100% them while revenging, YOU CAN STEAL 1,000,000 OF EACH RESOURCE. Plus an additional 5K DE.

Clash On!
EDIT: You can only revenge the goblins once you attack 10 times in multiplayer and you win at least 1 star each time. Your attacks reset after midnight.
But people wouldn't farm low to easily win ten times, because of the following reason:
If you are in bronze and you get attacked by the goblins, you can only steal the loot from the top 10 maps in single player. (Hence, people would try to trophy push).
