Honestly, save yourself a whole bunch of time, heartache and energy... Just leave the game. Plarium don't care about you or your enjoyment of the game, especially if you're not spending money.
Additionally, RSL life doesn't get much better with Arbiter. Sure you get to play in the Gold IV sandbox for months and months, drip feeding your great hall stats, but it's not like Arena becomes an enjoyable piece of content all the sudden.
You just minlessly drone on, skipping battles against 'real player teams' because the next page will be full of bot teams you just one shot and move on your day with.
Makes me laugh at how much of this game I don't actually play....Campaign farm, dungeon 20 spam, potion keeps, minotaur runs, and clan boss, are all run on auto through third party software. I'm not even watching, much less paying attention or enjoying them.
Arena and Tag Team Garbage is the only thing i pay half attention to but I wouldn't say thats out of enjoyment, just efficiency....
TLDR: @OP, don't bother getting invested in this game.
