Is it worth getting the Trials Pass?

Hoping to earn the Prestige Aatrox skin. I currently have 155 "2019 tokens" in my inventory and 1008 in my stash. The pass will give a attention 200, so 1355. A week to farm 700 tokens... while I'm working. Is this possible? If not... I believe I can only get tokens via wins/the pass until the 2nd of June. After this, will there be any more events/chances/ways to earn the remaining tokens I need before they expire?
