Galaxies Event question

So I want to purchase de Prestige True Damage Senna skin, and for that I have bought the event ticket so I could gather 2200 tokens. Seeing all my progress, I have completed every quest the event had and im stuck at 1655 tokens right now. I am wodnering if they are going to release a new set of quests so I can get to 2200? Otherwise, do you guys think Ill reach the goal by just playing games? Thank you and sorry for my english :c
