Ok so here's an idea.
Every Friday night, you get a certain amount of coins for logging in each day and playing at least an hour and getting at least 10 kills (so you can't just afk the whole time) up until that night. The coins you get goes up exponentially by two. So if you logged in 7 days in a row, you get 128 coins. These coins can be used in the event shop, where you can exchange 40 Weekly Coins for 1 EC piece. This means that for players who suck at events or just don't want to do events can get those OP weapons in the event shop, albeit slowly. At this rate, it would take a 63 weeks of consistant playing to get the Chemical Gun. Over a year. Do not just cry out "It's called an EVENT coin for a reason" because it doesn't matter, these weapons are made harder to get than they should be by people who crush all those in their way in events and don't ever let other players have a chance. I'm just suggesting this so it's just a little more fair.
