yup, there will be other events and basically just play the game and you’ll get there. Heck you’re 1/3rd of the way there already and end-date is August. No doubt will there be another event after that.
Just make sure you’re still enjoying the game and not logging in just to grind out the points for the T6, this way you won’t enjoy your grand prize because you’ll be burned out with the game by then.
As stated before, just playing the game at a normal pace you’ll rake in enough in-game currencies and event prizes to make it worth your while.
