I'd like the ability to NOT have to wait 24 hours to get a free skill point refill. The fairy dust is cheaper than the Energy potions, so we should get a ~30 sec for 1 skill point refill. Also, the energy refill is way too long. As cooper said, it should be reduced.
My personal plan is to get Goblin and Dwarf Engineer and all Titans, with the Unicorn Hero, Popo and Vigeraf. I just keep the hero's back and let the rest attack. The Dwarf and Goblins hold them off with their numbers until the titans come, and then I build a tower. It works on -Most- Levels.
