Update: Scam or not.
After a month into SWH and been playing consistently (missed a day or two throughout). The results are the same.
Arena top 5 still same players and IMO they are made up players (I could be wrong). If I'm wrong, they are not your average Joe. At one point we were almost the same level (low 50's). That same week the 70 lvl update hit and they literally smashed their way through into the high 50. Now somewhere in the low-mid 50 you're unable to level up in a day without spending a dime or even accumulating gems from arena. You would have to spend a decent amount of cash to level up and they jumped 3+ pts in a day (I'd do the math for ya but you can figure that yourselves). This is a similar scheme from a previous game I use to play called Castle Clash. They would use fake accounts (high level) to impress consumers to buy and upgrade. Actually, SWH does have the same concept. Especially the unlucky chromium packs.
Currently, I'm level 61 and wish I didn't spent a dime for gems in the beginning. You just have to play consistently and rank up in arena for gems. These are facts and opinion based on one month worth playing SWH. There are more unexplained s**t than this but I'll continue later...
Keep it 100
