Tornado should have 4 elixir because the kind of job it does... Just outclasses every card... It can avoide even a single hit from hog rider and baloon plus invokes king tower... making it even harder next time... so unfair to other cards... Plus card response time is 3 to 4 seconds... Even emotes take 2 secs... Clash royale has become so slow and unfair just like clash of clans...
