You get out of it what you put into it. Does climbing the Arena mean that much to you? If not, then don’t worry. Do what some of us already do which is collect the dinosaurs and level them up. I play the Arena with my theme teams for the daily battle incubators and to help my Alliance. It isn’t the be all and end all for me. I much prefer to go out and collect the dinosaurs.
To me, it still is this… up to a point. If you don’t boost (and that is fine) there is a point you can get to without them. As long as you are happy getting to that point, it’s fun and fine. In my opinion at least.
