New elixer type, troops, and defenses

With the new elixer type, the Light elixer, coc players could now farm a rare resource that's not dark elixer. With the light elixer there would be a light elixer barracks with the new troops the baby dragon, mystic, paladin, and assassin. Light elixer troops do double damage against dark elixer troops and vice versa. The Baby would be a flying unit that filled the same housing space as a minion but would follow the dragon troop. The paladin is a tank troop that would slightly heal the troops around it and have the same attack and health as the golem. The mystic would give the land troops around it a rage effect similar to a healer's heal effects. The assassin targets clan troops and Heroes and has the similar attack and housing space as a wizard. The defenses to defend againt these troops will be the sanctuary that will defend clan troops from spells and troops by a percentage. Another defense will be blessed tower that pops up like a hidden tesla but will cancel out a potential of an effect of a spell. Tell me what you think about this idea.

I don't think a new resource is needed judging by the current development of the game. Also, if there is a troop with the exact same stats as a another troop then why implement it?
