Change to lavahound lvl2 appearance

Im a th9, recently got my lavahound upgrade. Now as you kind of expect after an upgrade that the troops look would slightly improve right? (Different opinions on that). Well there isnt a change in appearance, and for a troop that has 3 levels there should be changing appearance after every upgrade.Personally i think if youre being made to work your ♥♥♥ off to get the resources for an upgrade, you should at least get a change in the troop appearance along with the added damage and whatnot. Wizards are a good example, wizards change appearance alot, they go from small fire balls to a more lightning type strike, change from blue, to black and white and then to full black. Dragons as well, always changing. So thats just a small suggestion.
