New troop concept

The only thing high level players use are golems, witches ect. Well to help with this problom would be a archer tower like defence that starts out doing lots of damage, (maybe 400 or so) but decreases by 5 every shot. I was thinking of a like shocking thing. That way people would need to use troops like barbs,archer ect to decrease the power of this defence. It would develop alot more stratagy in the game :) let me know what you think, i think it should be avalible at either town hall 8 or 9 and upgraded to lvl 2 at th10

thanks for feedback! And sorry for spelling i typed this up fast
