A Little Tip??

I already have the final reward skin for the Gadget Mayhem event, but it came out again this time. The reason I bothered to clear it again using tickets is because duplicate skins or emoticons are converted into gems. Emoticons and skins do have rarity tiers, and skins convert to 300 gems, while emoticons, though I don't remember the exact amount, were around a few tens of gems. I'm not sure if this differs by rarity tier, but I recently found out that duplicates are converted to gems. Since I needed gems to open the training bag this time, I cleared it using tickets and got 300 gems. Many of you might already know this, but if you didn't, it could be a useful tip. Hope this helps!
