Do EK a favour and stay where you are. The last thing they need is someone who lacks the command experience trying to jump the queue, although that has happened before.
Why uproot yourself, earn less for a job that could end up being a let down for you. You know what they say about the greener grass......Who knows you might not make the upgrade course or interview when you're number comes up - then you're really going to regret your decision.
Be warned, Rather stay put!
